> Project: HBase
> Issue Type: Bug
> Components: regionserver, Replication
> Affects Versions: 1.3.0
> Reporter: Ashu Pachauri
> Assignee: Joseph
> Priority: Blocker

> 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.
