I am running a date command with YARN's distributed shell example in a
loop of 1000 times in this way:
--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.
Is this a known issue? Or am I missing doing something? Please help.
Note: I am working on hadoop--2.0.0-alpha
