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

             Summary: TestReplicaWithCluster#testReplicaGetWithPrimaryAndMetaDown is a flaky
test
                 Key: HBASE-18289
                 URL: https://issues.apache.org/jira/browse/HBASE-18289
             Project: HBase
          Issue Type: Test
          Components: test
            Reporter: Mike Drob


Started looking into this today, spend about half the day, and couldn't finish it off, but
am filing this JIRA so that I can record progress somewhere and maybe somebody else with more
contextual knowledge can chime in.

I'll attach a truncated log file from one of the flaky job runs that focuses on only this
test.

We enable the regions are down simulation at 16:31:30 in the file, and we can see that reads
on the primary fail and then succeed on the replica for a while. There's a lot of stack traces
starting at that point, so I have trouble keeping track of when exactly the replica disappears.
Scans of the meta replica look like they work the whole time, it's the user table that fails.
