---------------------------------------
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.
