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

             Summary: Replication remove_peer gets stuck and blocks WAL rolling
                 Key: HBASE-16081
                 URL: https://issues.apache.org/jira/browse/HBASE-16081
             Project: HBase
          Issue Type: Bug
          Components: regionserver, Replication
            Reporter: Ashu Pachauri
            Assignee: Ashu Pachauri


We use a blocking take from CompletionService in HBaseInterClusterReplicationEndpoint. When
we remove a peer, we try to shut down all threads gracefully. But, under certain race condition,
the underlying executor gets shutdown and the CompletionService#take will block forever, which
means the remove_peer call will never gracefully finish.
Since ReplicationSourceManager#removePeer and ReplicationSourceManager#recordLog lock on the
same object, we are not able to roll WALs in such a situation and will end up with gigantic
WALs.
