------------------------------------
Summary: Slow JDBC fetch from Impala HS2
Key: HIVE-27873
URL: https://issues.apache.org/jira/browse/HIVE-27873
Project: Hive
Issue Type: Improvement
Components: JDBC
Reporter: Kurt Deschler
Assignee: Kurt Deschler
The fix for HIVE-20621 leads to poor performance fetching from Impala since
isHasResultSet is not set by Impala. The existing logic calls
getOperationStatus() on every row fetched which severely impacts fetch
performance and also results in a completion message being logged for each row.
