Vinod Kumar Vavilapalli resolved YARN-492.
    Resolution: Won't Fix

Agree with analysis from [~hitesh] and [~revans2]. Resolving this as won't fix.

May be YARN-220 can help though, if we come around to having a fix there.

> Too many open files error to launch a container

>                 Key: YARN-492
>                 URL: https://issues.apache.org/jira/browse/YARN-492
>             Project: Hadoop YARN
>          Issue Type: Bug
>    Affects Versions: 2.0.0-alpha
>         Environment: RedHat Linux
>            Reporter: Krishna Kishore Bonagiri
> I am running a date command with YARN's distributed shell example in a loop 
> of 1000 times in this way:
> yarn jar 
> /home/kbonagir/yarn/hadoop-2.0.0-alpha/share/hadoop/mapreduce/hadoop-yarn-applications-distributedshell-2.0.0-alpha.jar
>  org.apache.hadoop.yarn.applications.distributedshell.Client --jar 
> /home/kbonagir/yarn/hadoop-2.0.0-alpha/share/hadoop/mapreduce/hadoop-yarn-applications-distributedshell-2.0.0-alpha.jar
>  --shell_command date --num_containers 2
> Around 730th time or so, I am getting an error in node manager's log saying 
> that it failed to launch container because there are "Too many open files" 
> and when I observe through lsof command,I find that there is one instance of 
> this kind of file is left for each run of Application Master, and it kept 
> growing as I am running it in loop.
> node1:44871->node1:50010
> Thanks,
