Martin Kleppmann commented on SAMZA-276:
----------------------------------------
Does the tmp directory already exist by default? Might be safest to create it
explicitly in the shell script.
Also, I think it would be a bit safer to use an absolute path (e.g.
"$base_dir/tmp") rather than a relative path, in case something changes the
container's working directory after it starts up.
> Set -Djava.io.tmpdir to be usercache dir in YARN

> I don't believe we set -Djava.io.tmpdir in any of our shell scripts right
> now. When running Samza jobs in YARN, we should set -Djava.io.tmpdir to be
> the usercache directory or ./tmp or something, not /tmp on the root mount.
