----------------------------------
Summary: Unregister ReplicationSource metric bean when the
replication source thread is terminated
Key: HBASE-10093
URL: https://issues.apache.org/jira/browse/HBASE-10093
Project: HBase
Issue Type: Improvement
Components: Replication
Affects Versions: 0.94.14
Reporter: cuijianwei
Each replication source thread will register a metric bean to show its
statistics. The source threads will be terminated when region server exit and
the metric beans will be removed. However, replication source thread may also
be terminated when user removing the peer explicitly or it just takes a recover
queue and finished replicating the queued HLogs. In these situations, the
metric bean won't be unregistered and user may be confused to always see the
statistics from terminated replication source threads. Maybe, it is more clear
to remove the metric bean after replication source thread terminated? Then, the
statistics will only from active replication sources.
