-----------------------------

             Summary: Missing explanation of hidden maven artifacts needed for 2x
                 Key: PIG-3738
                 URL: https://issues.apache.org/jira/browse/PIG-3738
             Project: Pig
          Issue Type: Bug
            Reporter: jay vyas


Newcomers to pig will undoubtedly have trouble resolving issues such as this one: PIG-3729 .

The reason being that 

- pig compiles differently for 2x and 1x
- pig has a with and without hadoop artifact 

Thus, there are at least 4 different variants of the pig jar which will be relevant to different users.  

These need to be disambiguated.   And the presence/usage of hidden "provided" maven artifacts should also be illuminated .  

The place for this is probably https://cwiki.apache.org/confluence/display/PIG/Developer+Documentation , as mentioned in the last comment of the referenced (PIG-3729) JIRA. 

Although this is NOT a code bug... I think this is a very critical missing peice : and thus Ive filed this as a bug, although it really is just a documentation issue in the end.
