How Do I Improve the Resource Utilization of Core Nodes in a Cluster?

  1. Go to the Yarn service configuration page.
    • For versions earlier than 1.9.2,

      log in to MRS Manager, choose Services > Yarn > Service Configuration, and select All from the Basic drop-down list.

    • For MRS 1.9.2 or later, click the cluster name on the MRS console, choose Components > Yarn > Service Configuration, and select All from the Basic drop-down list.

      If the Components tab is unavailable, complete IAM user synchronization first. (On the Dashboard page, click Synchronize on the right side of IAM User Sync to synchronize IAM users.)

    • MRS 3.x or later: Log in to FusionInsight Manager. Choose Cluster > Name of the desired cluster > Services > Yarn > Configurations > All Configurations.
  2. Search for yarn.nodemanager.resource.memory-mb, and increase the value based on the actual memory of the cluster nodes.
  3. Save the change and restart the affected services or instances.
