Rohini Palaniswamy resolved MAPREDUCE-6576.
-------------------------------------------
Resolution: Duplicate
My bad. I thought I did not report this. But found that [~jlowe] had already reported this in MAPREDUCE-6472 and it is fixed in 2.7.2

> Key: MAPREDUCE-6576
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6576
> Project: Hadoop Map/Reduce
> Issue Type: Improvement
> Reporter: Rohini Palaniswamy
> Labels: newbie
>
> For tasks it is already done by MapReduceChildJVM
> {code}
> Path childTmpDir = new Path(Environment.PWD.$(),
> YarnConfiguration.DEFAULT_CONTAINER_TEMP_DIR);
> vargs.add("-Djava.io.tmpdir=" + childTmpDir);
> So it is only needed to be set for AM in launcher because of uber mode.
> {code}
> Need to do this in AM as well, so that running in uber mode does not go to default java.io.tmpdir of /tmp and fill up task nodes and not be cleanedup.
