> In the CommonJoinOperator, for outer joins, there is a loop over every row in the AbstractRowContainer checking for a filtered tag.  This can take a long time if there are a large number or rows, and during this time, it does not report progress.  If this runs for long enough, Hadoop will kill the task for failing to report progress.
