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

             Summary: [Flakey Test] TestReplicator#testReplicatorWithErrors: AssertionError: We did not replicate enough rows expected:<10> but was:<7>
                 Key: HBASE-23812
                 URL: https://issues.apache.org/jira/browse/HBASE-23812
             Project: HBase
          Issue Type: Bug
          Components: flakies
            Reporter: Michael Stack
            Assignee: Michael Stack
             Fix For: 3.0.0, 2.3.0


I've seen this fail. Here is the latest:
{code}
 [ERROR] Tests run: 2, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 21.044 s <<< FAILURE! - in org.apache.hadoop.hbase.replication.regionserver.TestReplicator
 [ERROR] org.apache.hadoop.hbase.replication.regionserver.TestReplicator.testReplicatorWithErrors  Time elapsed: 7.139 s  <<< FAILURE!

   at org.apache.hadoop.hbase.replication.regionserver.TestReplicator.testReplicatorWithErrors(TestReplicator.java:158)
{code}

In test logs there are a few (in groups of three) of these:
{code}

Let me fix this and see if it makes TestReplicator stable again.
