Isabel Drost-Fromm commented on MAHOUT-1325:
--------------------------------------------
Looks like this test still writes to "/tmp" due to the way we create the
content of the mrOutputDir. Finding tests that do that actually is pretty easy
- just set /tmp to be non-writeable for the time the tests are run - we should
find a way to enforce all our tests to only write to maven's target dir during
the build process though - I believe that the random testing dependency can
help with that, don't know the option at the top of my head though. Otherwise
people will accidentally add tests that ignore this practice - or fail to run
the above mentioned sanity check when fixing existing tests like I did.
I'll go and figure out how to teach that one little test to direct non of it's
output to tmp tomorrow though.
