Description

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.
