Deneche A. Hakim created DRILL-4657:
---------------------------------------
Summary: Rank() will return wrong results if a frame of data is
too big (more than 2 batches)
Key: DRILL-4657
URL: https://issues.apache.org/jira/browse/DRILL-4657
Project: Apache Drill
Issue Type: Bug
Components: Execution - Relational Operators
Affects Versions: 1.3.0
Reporter: Deneche A. Hakim
Assignee: Deneche A. Hakim
Priority: Critical
Fix For: 1.7.0
When you run a query with RANK, and one particular frame is too long to fit in
2 batches of data, you will get wrong result.
I was able to reproduce the issue in a unit test, thanks to the fact that we
can control the size of the batches processed by the window operator. I will
post a fix soon along with the unit test
