> Setting default tmp directory for java createTempFile (java.io.tmpdir)
> ----------------------------------------------------------------------
>
> Key: HADOOP-2735
> URL: https://issues.apache.org/jira/browse/HADOOP-2735
> Project: Hadoop Core
> Issue Type: New Feature
> Components: mapred
> Reporter: Koji Noguchi
> Assignee: Amareshwari Sri Ramadasu
> Priority: Critical
> Fix For: 0.16.1
>
> Attachments: patch-2735.txt, patch-2735.txt, patch-2735.txt

> On our cluster, we've seen Pig(http://incubator.apache.org/pig/) filling up
> the /tmp and failing.
> (also inefficient since all the local tasks were spilling to the same disk)
> Pig is simply using java api createTempFile,
> http://java.sun.com/j2se/1.5.0/docs/api/java/io/File.html#createTempFile(java.lang.String,%20java.lang.String,%20java.io.File
> Can we add -Djava.io.tmpdir="./tmp" somewhere ?
> so that,
> 1) Tasks can utilize all disks when using tmp
> 2) Any undeleted tmp files will be deleted by the tasktracker when task(job?)
> is done.
> The easiest way is to set it inside mapred.child.java.opts in the config, but
> this can be overwritten if the users set their own task heapsize.
