Szehon Ho commented on HIVE-6847:
---------------------------------

This seems like a nice addition, but wondering do we need to escape special characters in generating user-scratch dir, like the logic we use in generating the partition names (FileUtils.escapePathName)?  Also there is some extra formatting diffs, and it'd be clearer to see it in the review board if you could
