>                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6576
>             Project: Hadoop Map/Reduce

> 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.
