Do not perform high-risk management operations such as deleting objects on the page. If an operation is required, you are advised to perform the operation on each component after confirming that the operation has no impact on services. For example, you can use the HDFS client to perform operations on HDFS files and use the Hive client to perform operations on Hive tables.</p>
