> 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
