Joseph updated HBASE-16081: --------------------------- Status: Open (was: Patch Available) > 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 > Affects Versions: 1.3.0 > Reporter: Ashu Pachauri > Assignee: Joseph > Priority: Blocker > Attachments: HBASE-16081-v2.patch, HBASE-16081-v3.patch, > HBASE-16081-v4.patch, HBASE-16081.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
