----------------------------------

             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.
