Wellington Chevreuil commented on HBASE-22537:
----------------------------------------------
Hi [~sreenivasulureddy], confirmed this only happens on *branch-2.1* by
executing your additional test provided in this patch. One thing I noticed is
that even in *branch-2.1,* if I executed the whole test suite from
*TestSplitOrMergeStatus,* test *testSplitRegionReplicaRitRecovery* passes, but
if I run it individually, it fails. It seems this is because
*TestSplitOrMergeStatus* defines _BeforeClass/AfterClass,_ but we need to
run/shutdown mini cluster individually, for each test method. Can you change
*TestSplitOrMergeStatus.setUpBeforeClass* and
*TestSplitOrMergeStatus.t**earDownAfterClass* to non static, and to use
_Before/After ++_junit annotations? We may need to rename those methods
accordingly.
Also, I think this test would be good addition to other branches, to make sure
we don't face a regression. Can you create patch versions including the
additional test only, for both *master* and *branch-2* branches?
