> 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, 2.6.0
> Reporter: Noah Watkins
> Assignee: Brahma Reddy Battula
> Attachments: MAPRED-6136.patch
>
>
> 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.
