Hitesh Shah commented on TEZ-2787:
----------------------------------
No harm in doing so but given that it has not impacted anyone, it should be ok
to just backport to 0.7 only.
> Tez AM should have java.io.tmpdir=./tmp to be consistent with tasks

> Key: TEZ-2787
> URL: https://issues.apache.org/jira/browse/TEZ-2787
> Project: Apache Tez
> Issue Type: Bug
> Affects Versions: 0.7.0
> Reporter: Jason Lowe
> Assignee: Jonathan Eagles
> Attachments: TEZ-2787.1.patch, TEZ-2787.2.patch, TEZ-2787.3.patch

> TezRuntimeChildJVM ensures that tasks are launched with
> -Djava.io.tmpdir=./tmp, but there's no corresponding code to ensure the Tez
> AM also has a similar tmpdir setting. The client should setup the AM launch
> context to have -Djava.io.tmpdir=./tmp to be consistent with the tasks and to
> prevent accidental leaking of files in /tmp by the Tez AM if it crashes.
