Rohini Palaniswamy commented on OOZIE-2260:
-------------------------------------------
bq. File MAPREDUCE-6576, so that this issue is fixed in hadoop itself in future
Closed that one as duplicate as I had already filed it long back
(MAPREDUCE-6472 and TEZ-2787) and they are fixed.
> Only set "java.io.tmpdir" to "./tmp" for the AM

> OOZIE-2209 sets java.io.tmpdir to ./tmp for AM, map and reduce for both
> launcher and action jobs.
> MapReduceChildJVM already sets java.io.tmpdir to ./tmp
> {code}
> Path childTmpDir = new Path(Environment.PWD.$(),
> YarnConfiguration.DEFAULT_CONTAINER_TEMP_DIR);
> vargs.add("-Djava.io.tmpdir=" + childTmpDir);
> {code}
> So it is only needed to be set for AM in launcher because of uber mode.
