Jason Lowe created MAPREDUCE-6279: ------------------------------------- Summary: AM should explicity exit JVM after all services have stopped Key: MAPREDUCE-6279 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6279 Project: Hadoop Map/Reduce Issue Type: Improvement Affects Versions: 2.5.0 Reporter: Jason Lowe
Occasionally the MapReduce AM can "get stuck" trying to shut down. MAPREDUCE-6049 and MAPREDUCE-5888 were specific instances that have been fixed, but this can also occur with uber jobs if the task code inadvertently leaves non-daemon threads lingering. We should explicitly shutdown the JVM after the MapReduce AM has unregistered and all services have been stopped. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
