Aaron T. Myers updated HDFS-2913: --------------------------------- Component/s: ha > HA: Need a way to shutdown the Name Node > ---------------------------------------- > > Key: HDFS-2913 > URL: https://issues.apache.org/jira/browse/HDFS-2913 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: ha, name-node > Affects Versions: HA branch (HDFS-1623) > Reporter: Bikas Saha > Assignee: Bikas Saha > > Ideally, NameNode.stop() needs to be called because it will change the HA > state and shutdown all services. NameNode reference is not available > anywhere. Hence it is not possible to shutdown the name node gracefully. > A possible solution could be to have a Service interface that gets passed > down to components like FSNameSystem, via which they can inform the NameNode > about irrecoverable errors. NameNode could then decide to shutdown. -- This message is automatically generated by JIRA.
