Peter Bacsko commented on OOZIE-2858:
-------------------------------------
I realized it's even easier to create a temp file.
Just invoke {{TemporaryFolder.newFile()}}. It will be automatically deleted
after the testcase.
> HiveMain, ShellMain and SparkMain should not overwrite properties and config
> files locally

> We're generating files on the fly in many of our *Main classes.
> These are usually log4j.properties and hive-site.xml files (there may be
> others, but these are the ones I managed to find).
> We should check if these files are there in advance and don't overwrite them
> if they are present. We could log a warning in this case or merge the
> contents of the files with the things we want to write into it. There is an
> example for this in PigMain and log4j.properties.
