Make Yarn Node Manager services robust against shutdown -------------------------------------------------------
Key: MAPREDUCE-4022 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4022 Project: Hadoop Map/Reduce Issue Type: Sub-task Components: mrv2 Affects Versions: 0.24.0, 0.23.2 Reporter: Steve Loughran Assignee: Steve Loughran Priority: Minor Add the nodemanager bits of MAPREDUCE-3502 to shut down the Nodemanager services. This is done by checking for fields being non-null before shutting down/closing etc, and setting the fields to null afterwards -to be resilient against re-entrancy. No tests other than manual review. -- This message is automatically generated by JIRA.
