> 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
