-----------------------------------
Sorry to take so long to get back to this. It was a long break from work...
Thanks so much for taking this over. I like the way you've implemented this.

> Pig dies when one record in a LOAD of a billion records fails to parse. This
> is almost certainly not the desired behavior. elephant-bird and some other
> storage UDFs have minimum thresholds in terms of percent and count that must
> be exceeded before a job will fail outright.
> We need these limits to be configurable for Pig, globally. I've come to
> realize what a major problem Pig's crashing on bad records is for new Pig
> users. I believe this feature can greatly improve Pig.
> An example of a config would look like:
> pig.storage.bad.record.threshold=0.01
> pig.storage.bad.record.min=100
> A thorough discussion of this issue is available here:
