[jira] [Created] (DRILL-6626) Hash Aggregate: Index out of bounds
with small output batch size and spilling
Boaz Ben-Zvi created DRILL-6626:
-----------------------------------
Summary: Hash Aggregate: Index out of bounds with small output batch size and spilling
Key: DRILL-6626
URL: https://issues.apache.org/jira/browse/DRILL-6626
Project: Apache Drill
Issue Type: Bug
Components: Execution - Relational Operators
Affects Versions: 1.14.0
Reporter: Boaz Ben-Zvi
This new IOOB failure was seen while trying to recreate the NPE failure in DRILL-6622 (over TPC-DS SF1). The proposed fix for the latter (PR #1391) does not seem to make a difference.
This IOOB can easily be created with other large Hash-Agg queries that need to spill.
The IOOB was caused after restricting the output batch size (to force many), and the Hash Aggr memory (to force a spill):
