Andrew Purtell updated HBASE-22107: ----------------------------------- Summary: Periodically clean the dead server list (was: make dead server metric work for HBase in a compute fabric (e.g. YARN) use case) > Periodically clean the dead server list > --------------------------------------- > > Key: HBASE-22107 > URL: https://issues.apache.org/jira/browse/HBASE-22107 > Project: HBase > Issue Type: Improvement > Components: Operability > Reporter: Sergey Shelukhin > Priority: Minor > > dead servers appear to only be cleaned up when a server comes up on the same > host and port; however, if HBase is running on smth like YARN with many more > hosts than RSes, RS may come up on a different server and the dead one will > never be cleaned. > The metric should be improved to account for that... it will potentially > require configuring master with expected number of region servers, so that > the metric could be output based on that. > Dead server list should also be expired based on timestamp in such cases. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
