[jira] [Commented] (HBASE-24712) [Flaky] TestMasterNoCluster.testStopDuringStart on master

    [ https://issues.apache.org/jira/browse/HBASE-24712?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17155539#comment-17155539 ] 

Viraj Jasani commented on HBASE-24712:
--------------------------------------

[~stack] Based on the recent flaky reports, the test failures resolved in parent Jira (branch-2 and branch-2.3) should also be applied to master branch.

Raised PR and build is good, let me merge this and will monitor this test for some days. I am just forward-porting your patch with slight modification.

Thanks
