-------------------------------------

             Summary: Figure out why LocalIndexIT#testLocalIndexRoundTrip is flapping
                 Key: PHOENIX-3496
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3496
             Project: Phoenix
          Issue Type: Bug
            Reporter: Samarth Jain
            Assignee: Rajeshbabu Chintaguntla


The test has been passing consistently on the 4.*-HBase-0.98 branches. However, it has been
flapping pretty regularly on the master branch and the 4.*-HBase-1.1 branches.

I ran the test locally a few number of times and it did flap. I did notice that in cases where
it failed, the logs also had a RegionOpeningException. 
For example:

{code}
org.apache.hadoop.hbase.exceptions.RegionOpeningException: Region TEST_TABLET000060,\x07\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00,1479426366023.04f765e5d906bbd193b38a9f8c20e478.
