eric baldeschwieler commented on HADOOP-761:
--------------------------------------------

Using /tmp is simply not a good idea.  It leaves you vulnerable to various of system configuration differences, of which there are millions out there.  We should create temp files in the test's working directory.

> TestMiniMRLocalFS  test cases creates /tmp/wc/input/, which is not cleaned up, any other user running test on same machine simultaneously or later will see test failures. 
> It should either use a temp directory in the build/test or use java's File.createTempFile method for temporary data and then clean it up.
