----------------------------------------
Summary: Handle 0 length batches in LlapArrowRowRecordReader
Key: HIVE-22973
URL: https://issues.apache.org/jira/browse/HIVE-22973
Project: Hive
Issue Type: Bug
Components: llap
Reporter: Shubham Chaurasia
Assignee: Shubham Chaurasia
In https://issues.apache.org/jira/browse/HIVE-22856, we allowed
{{LlapArrowBatchRecordReader}} to permit 0 length arrow batches.
{{LlapArrowRowRecordReader}} which is a wrapper over
{{LlapArrowBatchRecordReader}} should also handle this.
On one of the systems (cannot be reproduced easily) where we were running test
{{TestJdbcWithMiniLlapVectorArrow}}, we saw following exception -
{code:java}
