Prashant Kommireddi commented on PIG-2541:
------------------------------------------
Dmitriy,
I was thinking some more about storing schema. In what case would schema for
"source path" need to be registered under the hood? I would assume a user will
always need to reference "source path" before using it, in which case storing
schema would occur as is done currently?

> There are a lot of interests in knowing where the data comes from when
> loading from a directory (or a set of directories). One can do it manually
> (see https://cwiki.apache.org/confluence/display/PIG/FAQ). But it will be
> more convenient for users if we implement this in the PigStorage with a
> command line option (e.g., pig.source.tagging=true/false) to turn it on/off.
> By default it will be off.
