[jira] [Created] (DRILL-3345) TestWindowFrame fails to properly check cases involving multiple batches

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

             Summary: TestWindowFrame fails to properly check cases involving multiple batches
                 Key: DRILL-3345
                 URL: https://issues.apache.org/jira/browse/DRILL-3345
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.1.0
            Reporter: Deneche A. Hakim
            Assignee: Deneche A. Hakim
            Priority: Critical
             Fix For: 1.1.0


as part of adding unit tests to TestWindowFrame, I added a debug option to MSorter to force the batches passed downstream to be of a specific size. This was supposed to help test edge cases involving multiple data batches while controlling precisely when a partition and/or window frame ends in a batch.

Turns out the change to MSorter was incomplete and all cases end up processing one single big batch of data.

The purpose of this JIRA issue is to fix this, add some check to detect when the batches are no longer split correctly and make sure all unit tests are passing.
