Cascalog's errors are pretty bad and confuse new users. A non-exhaustive list of bad spots includes:

1. Trying to output to a local tap under Hadoop
2. Trying to write to a directory that already exists
3. Passing functions in a Cascalog query
4. "Unable to join predicates" -- should provide more information
