> h2. What is the purpose of this change
>  * Fixing a flaky test to avoid shared state pollution {{org.apache.hadoop.hbase.replication.regionserver.TestDrainReplicationQueuesForStandBy.test}}
> h2. Reproduce the test failure
>  * Run the test twice in the same JVM.
> h2. Expected result:
>  * The test should run successfully when multiple tests that use this state are run in the same JVM.
> h2. Actual result:
>  * We get the failure:
>  {{org.apache.hadoop.hbase.DoNotRetryIOException: Can not transit current cluster state from STANDBY to STANDBY for peer id=1}}
> h2. Why the test fails
>  * When the test ends, current cluster for peer id=1 is STANDBY, it can not be transitted from STANDBY to STANDBY.
> h2. Fix
>  * Reset the state when test ends.
