Subject [jira] Created: (PIG-1106) FR join should not spill
Date Wed, 25 Nov 2009 01:26:39 GMT
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
