---------------------------------------
Summary: MRAppMaster doesn't shutdown file systems
Key: MAPREDUCE-6136
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6136
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: applicationmaster
Affects Versions: 2.4.1
Reporter: Noah Watkins
When MRAppMaster exit it doesn't call close on its open file systems instances.
MAPREDUCE-3614 sets conf.setBoolean("fs.automatic.close", false); in
MRAppMaster::main and then called FileSystem.closeAll() in
MRAppMasterShutdownHook.
However, MAPREDUCE-4205 removed the call to FileSystem.closeAll()
MRAppMasterShutdownHook but left `fs.automatic.close` set to false.
Removing `conf.setBoolean("fs.automatic.close", false);` worked for me, but it
wasn't clear if this had other implications.
