Nandor Kollar commented on PIG-5167:
------------------------------------
It seem that this fails, because we can't rely on the order of rows. As per Pig
documentation (https://pig.apache.org/docs/r0.16.0/basic.html#limit):
"If the specified number of output tuples is less than the number of tuples in
the relation, then n tuples are returned. There is no guarantee which n tuples
will be returned, and the tuples that are returned can change from one run to
the next. A particular set of tuples can be requested using the ORDER operator
followed by LIMIT."
> Limit_4 is failing with spark exec type
