-----------------------------------

             Summary: For outer joins, when looping over the rows looking for filtered tags,
it doesn't report progress
                 Key: HIVE-3916
                 URL: https://issues.apache.org/jira/browse/HIVE-3916
             Project: Hive
          Issue Type: Bug
          Components: Query Processor
    Affects Versions: 0.11.0
            Reporter: Kevin Wilfong
            Assignee: Kevin Wilfong


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.
