FR join should not spill
------------------------
Key: PIG-1106
URL: https://issues.apache.org/jira/browse/PIG-1106
Project: Pig
Issue Type: Bug
Reporter: Olga Natkovich
Assignee: Ankit Modi
Fix For: 0.7.0
Currently, the values for the replicated side of the data are placed in a
spillable bag (POFRJoin near line 275). This does not make sense because the
whole point of the optimization is that the data on one side fits into memory.
We already have a non-spillable bag implemented (NonSpillableDataBag.java) and
we need to change FRJoin code to use it. And of course need to do lots of
testing to make sure that we don't spill but die instead when we run out of
memory
