Dawid Weiss commented on MAHOUT-916:
------------------------------------
You'd have to check but I bet /tmp is based off a system property
java.io.tmpdir. For Lucene this is solved by setting:
{code}
<sysproperty key="java.io.tmpdir" value="." />
{code}
again - this works because randomized testing splits the cwd for each forked
JVM, but perhaps you could set up a class rule on hadoop tests that would
"temporarily"? set up a sub-tmp folder and override this property. Might work.
