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

             Summary: [0.92 UNIT TESTS] TestReplication.queueFailover occasionally fails [Part-2]
                 Key: HBASE-6733
                 URL: https://issues.apache.org/jira/browse/HBASE-6733
             Project: HBase
          Issue Type: Bug
            Reporter: Devaraj Das
             Fix For: 0.92.3


The failure is in TestReplication.queueFailover (fails due to unreplicated rows). I have come
across two problems:
1. The sleepMultiplier is not properly reset when the currentPath is changed (in ReplicationSource.java).
2. ReplicationExecutor sometime removes files to replicate from the queue too early, resulting
in corresponding edits missing. Here the problem is due to the fact the log-file length that
the replication executor finds is not the most updated one, and hence it doesn't read anything
from there, and ultimately, when there is a log roll, the replication-queue gets a new entry,
and the executor drops the old entry out of the queue.
