Benjamin Reed commented on PIG-570:
-----------------------------------

Ah sorry, i did the patch with respect to trunk. i'll regen. it is probably 
possible to create a smaller test case, but it will take awhile. i did simple 
brute force trial an error to get the test case. (i thought it was pretty good 
that i was able to keep it to under 2M :) are you concerned about the size or 
the run time?

> So I don't believe  bzip2 input to pig is working, at least not with large 
> files. It seems as though map files are getting cut off. The maps complete 
> way too quickly and the actual row of data that pig tries to process often 
> randomly gets cut, and becomes incomplete. Here are my symptoms:
> - Maps seem to be completing in a unbelievably fast rate
> With uncompressed data
