[jira] [Created] (DRILL-3294) False schema change exception in CTAS
with AVG window function
Victoria Markman created DRILL-3294:
---------------------------------------
Summary: False schema change exception in CTAS with AVG window function
Key: DRILL-3294
URL: https://issues.apache.org/jira/browse/DRILL-3294
Project: Apache Drill
Issue Type: Bug
Components: Execution - Relational Operators
Affects Versions: 1.0.0
Reporter: Victoria Markman
Assignee: Chris Westin
This bug could be related to DRILL-3293, but since it's a different function and different symptom, I'm filing a new one.

Query works correctly by itself:
