Automatic record provenance (source tagging) for PigStorage
-----------------------------------------------------------
Key: PIG-2541
URL: https://issues.apache.org/jira/browse/PIG-2541
Project: Pig
Issue Type: Improvement
Components: impl
Affects Versions: 0.9.1
Reporter: Richard Ding
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.
