Summary: External Sort encountered an error while spilling to disk
Key: DRILL-5226
URL: https://issues.apache.org/jira/browse/DRILL-5226
Project: Apache Drill
Issue Type: Bug
Components: Execution - Relational Operators
Affects Versions: 1.10.0
Reporter: Rahul Challapalli
Environment :
{code}
git.commit.id.abbrev=2af709f
DRILL_MAX_DIRECT_MEMORY="32G"
DRILL_MAX_HEAP="4G"
Nodes in Mapr Cluster : 1
Data Size : ~ 0.35 GB
No of Columns : 1
Width of column : 256 chars
{code}
The below query fails before spilling to disk due to wrong estimates of the
record batch size.
