Permission Verification Policies

Security Mode

After a user is authenticated by the big data platform, the system determines whether to verify the user's permission based on the actual permission management configuration to ensure that the user has limited or all permission on resources. If the user does not have the permission for accessing cluster resources, the system administrator must grant the required permission to the user. Otherwise, the user fails to access the resources. The cluster provides permission verification capabilities in both security mode and normal mode. The specific permission items of the components are the same in the two modes.

By default, the Ranger service is installed and Ranger authentication is enabled for a newly installed cluster in security mode. You can set fine-grained security access policies for accessing component resources through the permission plug-in of the component. If Ranger authentication is not required, administrators can manually disable it on the service page. After Ranger authentication is disabled, the system continues to perform permission control based on the role model of MRS Manager when accessing component resources.

In a cluster in security mode, the following components support Ranger authentication: HDFS, YARN, Kafka, Hive, HBase, Storm,, Impala, and Spark2x.

Hardening LDAP

LDAP is hardened as follows after a cluster is installed:

  • In the LDAP configuration file, the password of the administrator account is encrypted using SHA. After the OpenLDAP is upgraded to 2.4.39 or later, data is automatically synchronized between the active and standby LDAP nodes using the SASL External mechanism, which prevents disclosure of the password.
  • The LDAP service in the cluster supports the SSLv3 protocol by default, which can be used safely. When the OpenLDAP is upgraded to 2.4.39 or later, the LDAP automatically uses TLS1.0 or later to prevent unknown security risks.

Switching Ranger Authentication

Scenario

By default, the Ranger service is installed and Ranger authentication is enabled for a newly installed cluster in security mode. You can set fine-grained security access policies for accessing component resources through the permission plug-in of the component. If Ranger authentication is not required, the cluster administrator can manually disable Ranger authentication on the service page. After Ranger authentication is disabled, the system continues to perform permission control based on the role model of MRS Manager when accessing component resources.

In a cluster upgraded from an earlier version, Ranger authentication is not used by default when users access component resources. The cluster administrator can manually enable Ranger authentication after installing the Ranger service.

  • In a cluster in security mode, the following components support Ranger authentication: HDFS, YARN, Kafka, Hive, HBase, Storm,, Impala, and Spark2x.
  • In a cluster in non-security mode, Ranger supports permission control on component resources based on OS users. The following components support Ranger authentication: HBase, HDFS, Hive, Spark2x, and YARN.
  • After Ranger authentication is enabled, all authentication of the component will be managed by Ranger. The permissions set by the original authentication plug-in will become invalid (The ACL rules of HDFS and YARN components still take effect). Exercise caution when performing this operation. You are advised to deploy permissions on Ranger in advance.
  • After Ranger authentication is disabled, all authentication of the component will be managed by the permission plug-in of the component. The permission set on Ranger will become invalid. Exercise caution when performing this operation. You are advised to deploy permissions on Manager in advance.

    To facilitate user permission management, use fine-grained policies rather than RBAC policies. In fine-grained policies, the Deny action takes precedence over other actions.

    • A user has permission to synchronize IAM users only when the user has the Tenant Administrator role or has the Server Administrator, Tenant Guest, and MRS Administrator roles at the same time.
    • A user with the action:mrs:cluster:syncUser policy has permission to synchronize IAM users.

    5. After a synchronization request is sent, choose Operation Logs in the left navigation pane on the MRS console to check whether the synchronization is successful. For details about the logs, see Viewing MRS Operation Logs.
    6. After the synchronization is successful, use the user synchronized with IAM to perform subsequent operations.

      • When the policy of the user group to which the IAM user belongs changes from MRS ReadOnlyAccess to MRS CommonOperations, MRS FullAccess, or MRS Administrator, wait for 5 minutes until the new policy takes effect after the synchronization is complete because the SSSD (System Security Services Daemon) cache of cluster nodes needs time to be updated. Then, submit a job. Otherwise, the job may fail to be submitted.

      Cluster Nodes

      MRS provides three types of nodes:

      • Master: A Master node in an MRS cluster manages the cluster, assigns executable cluster files to Core nodes, traces the execution status of each job, and monitors the DataNode running status.
      • Core: A Core node in a cluster processes data and stores process data in HDFS. Analysis Core nodes are created in an analysis cluster. Streaming Core nodes are created in a streaming cluster. Both analysis and streaming Core nodes are created in a hybrid cluster.
      • Task: A Task node in a cluster is used for computing and does not store persistent data. Yarn and Storm are mainly installed on Task nodes. Task nodes are optional, and the number of Task nodes can be zero. Analysis Task nodes are created in an analysis cluster. Streaming Task nodes are created in a streaming cluster. Both analysis and streaming Task nodes are created in a hybrid cluster.
        When the data volume change is small in a cluster but the cluster's service processing capabilities need to be remarkably and temporarily improved, add Task nodes to address the following situations:
        • Service volumes temporarily increase, for example, report processing at the end of the year.

              Modify the following parameters based on service requirements and click OK.

              • Repeat: If selected, the resource configuration group runs repeatedly based on the scheduling period. If not selected, set the date and time when the configuration of the group of resources can be applied.
              • Repeat Policy: can be set to Daily, Weekly, and Monthly. This parameter is valid only when Repeat is selected.
              • Between: indicates the time period between the start time and end time when the resource configuration is applied. Set a unique time range. If the time range overlaps with that of an existing group of resource configuration, the time range cannot be saved. This parameter is valid only when Repeat is selected.
              • The default group of resource configuration takes effect in all undefined time segments.
              • The newly added resource group is a parameter set that takes effect dynamically in a specified time range.
              • The newly added resource group can be deleted. A maximum of four resource configuration groups that take effect dynamically can be added.
              • Select a repetition policy. If the end time is earlier than the start time, the next day is labeled by default. For example, if a validity period ranges from 22:00 to 06:00, the customized resource configuration takes effect from 22:00 on the current day to 06:00 on the next day.
              • If the repeat policy types of multiple configuration groups are different, the time ranges can overlap. The policy types are listed as follows by priority from low to high: daily, weekly, and monthly. The following is an example. There are two resource configuration groups using the monthly and daily policies, respectively. Their application time ranges in a day overlap as follows: [04:00 to 07:00] and [06:00 to 08:00]. In this case, the configuration of the group that uses the monthly policy prevails.
              • If the repeat policy types of multiple resource configuration groups are the same, the time ranges of different dates can overlap. For example, if there are two weekly scheduling groups, you can set the same time range on different day for them, such as to 04:00 to 07:00, on Monday and Wednesday, respectively.

              How Do I Interconnect MRS with LTS?

              +

              Prerequisites

              You have obtained the account AK and SK. For details, see How Do I Manage Access Keys?

              +
              +

              Procedure

              1. Install ICAgent on the MRS node. For details, see Installing ICAgent.

                For the first installation, install one server first, and then batch install all other hosts in the same way.

                +
                +
              2. Create a host group and add the ICAgent host installed in 1 to the host group.
                1. Log in to the Log Tank Service (LTS) console, and choose Host Management in the left navigation pane. On the displayed page, click Create Host Group in the upper right corner.
                2. In the Create Host Group slide-out panel that is displayed, enter a host group name in the Host Group field and set Host OS to Linux or Windows.
                3. In the host list, select one or more hosts to add to the group and click OK.
                  • You can filter hosts by host name or host IP address. You can also click Search by Host IP Address and enter multiple host IP addresses in the displayed search box to search for matches.
                  • If your desired hosts are not in the list, click Install ICAgent. In the Install ICAgent slide-out panel displayed, install ICAgent on the hosts as prompted.
                  +
                +
              3. Create a log group.
                1. Log in to the LTS console. On the Log Management page, click Create Log Group.
                2. In the Create Log Group slide-out panel displayed, enter a log group name. A log group name:
                  • Can contain only letters, numbers, hyphens (-), underscores (_), and periods (.).
                  • Cannot start with a period (.) or underscore (_), and cannot end with a period (.).
                  • Can contain 1 to 64 characters.
                  +
                3. Select an enterprise project. You can click View Enterprise Projects to view all enterprise projects.
                4. Set Log Retention Duration. The system stores logs for 30 days by default. You can change the log retention duration after the log group is created.

                  LTS offers a free quota of 500 MB per month for log read/write, retention, and indexing. When the free quota is used up, you will be billed for excess usage on a pay-per-use basis.

                  +
                5. Click OK.
                  • On the Log Management page, you can view log group details, including name, retention duration, creation time, creation type, and tags. You can also modify retention duration and tags. Click Modify in the Operation column of the log group to modify the name and retention duration.
                  • Click the log group name to access the log stream details page.
                  +
                +
              4. Create a log stream.
                1. On the LTS console, click the expansion button of a log group.
                2. Click Create Log Stream. In the Create Log Stream slide-out panel displayed, enter a log stream name. A log stream name:
                  • Can contain only letters, numbers, hyphens (-), underscores (_), and periods (.).
                  • Cannot start with a period (.) or underscore (_), and cannot end with a period (.).
                  • Can contain 1 to 64 characters.
                  +
                3. Select an enterprise project. You can click View Enterprise Projects to view all enterprise projects.
                4. Click OK.

                  On the log stream page, you can view details of the log stream, including log stream name, enterprise project, log retention duration, creation time, and creation type.

                  +

                  You can configure different log streams for different components.

                  +
                  +
                +
              5. Add hosts for log ingestion.
                1. In the navigation pane of the LTS management console, choose Log Ingestion > Ingestion Center.
                2. On the All tab page displayed, click Elastic Cloud Server (ECS).
                3. In the Select Log Stream step, set Log Group and Log Stream to the created log group and log stream name, and click Next.
                4. In the (Optional) Select Host Group step, select the host group created in 2 and click Next.
                5. In the Collections step, set Collection Configuration Name and Collection Paths, and click Next.

                  Path configurations

                  +
                  • You can configure multiple collection paths by clicking Add Collection Path.
                  • Each collection path must be unique. That is, the same path of the same host cannot be configured for different log groups and log streams.
                  • Collection paths support recursion. You can use double asterisks (**) to collect logs from up to five directory levels.
                  • Collection paths support fuzzy match. You can use an asterisk (*) to represent one or more characters of a directory or file name.
                  • If the collection path is set to a directory (such as /var/logs/), only .log, .trace, and .out files in the directory are collected.
                  +
                  +

                  For example, configure the following collection paths:

                  +

                  YARN task log path:

                  +
                  /srv/BigData/*/nm/containerlogs/**/container-localizer-syslog
+/srv/BigData/*/nm/containerlogs/**/directory.info
+/srv/BigData/*/nm/containerlogs/**/launch_container.sh
+/srv/BigData/*/nm/containerlogs/**/prelaunch.err
+/srv/BigData/*/nm/containerlogs/**/prelaunch.out
+/srv/BigData/*/nm/containerlogs/**/stderr
+/srv/BigData/*/nm/containerlogs/**/stdout
+/srv/BigData/*/nm/containerlogs/**/syslog*
+/srv/BigData/*/nm/containerlogs/**/*.log
                  +

                  All HDFS service logs:

                  +
                  /var/log/Bigdata/audit/hdfs/jn/hdfs-audit-journalnode.log
+/var/log/Bigdata/audit/hdfs/jn/SecurityAuth.audit
+/var/log/Bigdata/hdfs/*/
                  +

                  Configure log collection paths for other components by referring to HDFS service logs.

                  +
                6. Skip the Index Settings step and submit.

                  For details about how to configure index settings, see the Log Tank Service User Guide.

                  +
                  +
                +
              6. View the logs.
                1. Log in to the LTS console and choose Log Management in the navigation pane.
                2. In the Log Group Name column, click the name of the created log group to view logs.
