Daniel Dai commented on PIG-1838:
---------------------------------
What we do is put the following lines into pig-cluster-hadoop-site.xml:
{code}
<property>
<name>mapred.child.java.opts</name>
<value> -Djava.io.tmpdir=xxxx</value>
</property>
{code}
And put directory containing pig-cluster-hadoop-site.xml in classpath. Pig will
take it.

> Key: PIG-1838
> URL: https://issues.apache.org/jira/browse/PIG-1838
> Project: Pig
> Issue Type: Wish
> Components: impl
> Affects Versions: 0.8.0
> Reporter: Allen Wittenauer
>
> We're starting to see issues where interactive/command line pig users blow up
> due to so many large jar creations in /tmp. (In other words, pig execution
> prior to the java.io.tmpdir fix that Hadoop makes can kick in.) Pig should
> probably not depend upon users being savvy enough to override java.io.tmpdir
> on their own in these situations and/or a better steward of the space it does
> use.
