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

             Summary: ReplicationOperations().drain(..) may return too quickly
                 Key: ACCUMULO-4389
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-4389
             Project: Accumulo
          Issue Type: Bug
            Reporter: Josh Elser
            Assignee: Josh Elser
            Priority: Critical
             Fix For: 1.7.3, 1.8.0


Was taking a look at some logs from automated tests that [~romil.choksi] sent my way and noticed that MultiInstanceReplicationIT was failing infrequently.

Looking at the output, I can see that the call was returning very quickly (essentially in the amount of time the RPC would take on the slow test hardware)

{noformat}
Drain completed in 25ms
{noformat}

Looking at the implementation of {{MasterClientServiceHandler.drainReplicationTable(...)}}, it's not handling the references we read from the metadata table correctly. I believe this is causing the test to return too quickly.
