Rushabh S Shah commented on HBASE-23000:
----------------------------------------

I did some analysis yesterday. Found the commit that caused these tests to fail.
This is the jira: https://issues.apache.org/jira/browse/HBASE-22627
I reverted just 1  commit from branch-1.3 head  and ran all the failing tests 
and it succeeded. See the results below.
