Description

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.
