Description

Right now, we get messages like:

org.apache.hadoop.security.AccessControlException: Permission denied: user=admin, access=WRITE, inode="/user/beeswax/warehouse":hue:hive:drwxrwxr-x)

I feel we can further humanize such strings, to perhaps read like (just an example, looking for your comments as well):

org.apache.hadoop.security.AccessControlException: Permission denied for WRITE access for user 'admin' on path "/user/beeswax/warehouse" (hue:hive drwxrwxr-x).
