Russell Jurney commented on PIG-3157:
-------------------------------------
It could be an alias for SIZE. Two differences:
1) Occasionally SIZE() will complain of not being able to work on some types.
Not sure whats up, but LENGTH(chararray) works in these situations.
2) atm LENGTH only works for chararrays
> Move LENGTH from Piggybank to builtin, make LENGTH work for multiple types
> similar to SIZE
