Perusing the input data to a failed map task

[Greg Langmead]

Pig 0.8 executes my script by running six jobs. One of them is identified as
"MAP_ONLY" and it always fails, with the innermost error I can find either
saying "GC overhead limit exceeded" or "Java heap space". I suspect I have a
piece that is too large. How can I get my hands on the actual data it was
processing, so I can ascertain the cause? The task log says "Input records
from tmp1872359169" can I view that data?

Thanks,
