YARN-11626. Optimize ResourceManager's operations on Zookeeper metadata

Open XbaoWu opened this issue 1 year ago • 1 comments

Description of PR

For more information about this PR, please refer to the following issue: YARN-11626 Optimization of the safeDelete operation in ZKRMStateStore

The NoNodeException clearly indicates that the Znode no longer exists, so if we check again and find that the node does not actually exist, we can safely ignore this exception to avoid triggering a larger impact on the cluster caused by ResourceManager failover.

How was this patch tested?

add TestCheckRemoveZKNodeRMStateStore.testSafeDeleteZKNode()

For code changes:

  • [x] Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?
  • [x] Object storage: have the integration tests been executed and the endpoint declared according to the connector-specific documentation?
  • [x] If adding new dependencies to the code, are these dependencies licensed in a way that is compatible for inclusion under ASF 2.0?
  • [ ] If applicable, have you updated the LICENSE, LICENSE-binary, NOTICE-binary files?
