Olga Natkovich commented on PIG-2209:
-------------------------------------
My concern is that the data is generated by one set of users but used by
another and I am not sure how well we have tested the code that messages the
data since that was not a very common use case.
I could howevere see that if the schema file is not there nothing changes which
could be good enough. I do recommend that we at least add more test case for
schema provided both in file and in load statement
> JsonMetadata fails to find schema for glob paths
