[jira] [Created] (HBASE-25334) TestRSGroupsFallback.testFallback is flaky

Xiaolin Ha created HBASE-25334:
----------------------------------

             Summary: TestRSGroupsFallback.testFallback is flaky
                 Key: HBASE-25334
                 URL: https://issues.apache.org/jira/browse/HBASE-25334
             Project: HBase
          Issue Type: Test
            Reporter: Xiaolin Ha
            Assignee: Xiaolin Ha


Like in CI test results of PR [https://github.com/apache/hbase/pull/2699,]

failed UTs site is [https://ci-hadoop.apache.org/job/HBase/job/HBase-PreCommit-GitHub-PR/job/PR-2699/3/artifact/yetus-jdk8-hadoop3-check/output/patch-unit-hbase-server.txt]

 

In this unit test, it checks if all table regions assigned after balance, and then assert for the RS group of regions.

But balance() uses aync move, so just checking if regions are assigned is not enough. 

All movement operations will create TransitRegionStateProcedure, so I think using check for the number of active executors in MasterProcedureExecutor is better.
