[jira] [Commented] (SAMZA-276) Set -Djava.io.tmpdir to be usercache dir in YARN

["Martin Kleppmann (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SAMZA-276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14027588#comment-14027588 ] 

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.

> 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.
