Description

For tasks it is already done by MapReduceChildJVM

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.

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.
