Olga Natkovich commented on PIG-565:
------------------------------------
DIFF handles all the types as expected. However, the documentation in 0.7.0
release is slightly of.
Current docs: "The DIFF function compares two fields in a tuple. If the field
values match, null is returned. If the field values do not match, the
non-matching elements are returned."
Should say something like:
"DIFF takes two bags as arguments and compares them. Any tuples that are in
one bag but not the other are returned in a bag. If the bags match an empty bag
is returned. If the fields are not bags then they will be wrapped in tuples
and returned in a bag if they do not match, or an empty bag will be returned if
the two records match. The implementation assumes that both bags being passed
to this function will fit entirely into memory simultaneously. If that is not
the case the UDF will still function, but it will be <strong>very</strong>
slow."
I will reassign this bug to Corinne once I am done with it.
