[jira] [Created] (HBASE-25820) Find a way to know whether logQueue goes empty when ReplicationSource is running on ReplicationServer

Sun Xin created HBASE-25820:
-------------------------------

             Summary: Find a way to know whether logQueue goes empty when ReplicationSource is running on ReplicationServer
                 Key: HBASE-25820
                 URL: https://issues.apache.org/jira/browse/HBASE-25820
             Project: HBase
          Issue Type: Sub-task
            Reporter: Sun Xin


HBASE-25110 we choose to use ZK to notify ReplicationServer that a new wal was generated, this is asynchronous. And then we got a problem, the shipper thread and the wal reader thread may go terminated as logQueue goes empty before receiving the notification of new wal.

So we now need find a way to know whether logQueue is really empty after the last wal in logQueue is consumed.
