Olga Natkovich commented on PIG-2209:
-------------------------------------
Our users especially production ones are not very keen on changing their
processes.
I think this probably an ok change since our users do not have schema files
right now. I am worried that we have done such a major re-work of PigStorage
which is one of the main ways to get the data and how much problem we will see
as the result like the one we are seeing in the bug
> JsonMetadata fails to find schema for glob paths
