Ashu Pachauri updated HBASE-14953: ---------------------------------- Status: Patch Available (was: Open) > HBaseInterClusterReplicationEndpoint: Do not retry the whole batch of edits > in case of RejectedExecutionException > ----------------------------------------------------------------------------------------------------------------- > > Key: HBASE-14953 > URL: https://issues.apache.org/jira/browse/HBASE-14953 > Project: HBase > Issue Type: Bug > Components: Replication > Affects Versions: 2.0.0, 1.2.0, 1.3.0 > Reporter: Ashu Pachauri > Assignee: Ashu Pachauri > Priority: Critical > Attachments: HBASE-14953-V1.patch, HBASE-14953-V2.patch > > > When we have wal provider set to multiwal, the ReplicationSource has multiple > worker threads submitting batches to HBaseInterClusterReplicationEndpoint. In > such a scenario, it is quite common to encounter RejectedExecutionException > because it takes quite long for shipping edits to peer cluster compared to > reading edits from source and submitting more batches to the endpoint. > The logs are just filled with warnings due to this very exception. > Since we subdivide batches before actually shipping them, we don't need to > fail and resend the whole batch if one of the sub-batches fails with > RejectedExecutionException. Rather, we should just retry the failed > sub-batches. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
