Re: pig unit with pig 0.14?

[Billy Watson <wi...@gmail.com>]

It looks like a similar question was asked before. The solution might be to
check the job tracker logs for more information to see what's going on.

I've often found that to be the case, BTW. That checking the initial log
isn't enough. Either you have to check the job tracker log OR in the
initial error message, it might say some log file on your local machine
contains more info. Check that log file.

Here's the thread I was referring to:
