Ashu Pachauri created HBASE-14953: ------------------------------------- Summary: 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
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)
