Ashutosh Chauhan commented on PIG-2605:
---------------------------------------

Perhaps, Pig can automatically find out dependencies, but it may have other 
unwanted side-effects.
                
> UDF/LoadFunc/StoreFunc should have ability to specify their dependcies.

> In absence of this feature, user is forced to register all the internal 
> dependencies which LF/SF/UDF have. Hard part is not to do register itself, 
> but to figure out dependencies LF/SF have which is non-trivial since user has 
> not written those LF/SF/UDF herself.
> Perhaps, this will be considered in UDF/LF/SF redesign.
