Cheolsoo Park updated PIG-3059:
-------------------------------

    Attachment: PIG-3059.patch

Hi Joe,

I am sorry if you're working on this jira. But I was working for a customer who has issues with bad input files, so I thought that I might just solve it once for all.

As per your suggestion, I moved the error handling code to {{PigRecordReader}}, so now threshold should work for any record reader including {{PigAvroRecordReader}}. I uploaded the patch to the RB for your review:
https://reviews.apache.org/r/8765/

Please let me know what you think.

Thanks!

> 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: http://www.quora.com/Big-Data/In-Big-Data-ETL-how-many-records-are-an-acceptable-loss
