mapred.child.ulimit in MR2
Hi yarn-dev/mapreduce-dev,
Is there a reason that mapred.child.ulimit no longer has an effect in MR2?
Should it be added back in?
thanks for any help,
-Sandy

Actually, ulimit never worked correctly - we should probably not bother?

Sandy,
I think it was something that was missed in the port to YARN and the dead
code was cleaned up as part of HADOOP-8288.
If you have a use case for it or are worried about backwards compatibility
we can add it back in. It is not that hard, all it did was add 'ulimt -v
<number>' to the shell script that launched the task, except on windows.

Sandy,
I think it was something that was missed in the port to YARN and the dead
code was cleaned up as part of HADOOP-8288.
If you have a use case for it or are worried about backwards compatibility
we can add it back in. It is not that hard, all it did was add 'ulimt -v
<number>' to the shell script that launched the task, except on windows.
