--------------------------------------------
Summary: GetOperationStatus called in resultset.next causing
incremental slowness
Key: HIVE-20621
URL: https://issues.apache.org/jira/browse/HIVE-20621
Project: Hive
Issue Type: Bug
Components: JDBC
Affects Versions: 4.0.0, 3.2.0
Environment: Fetching result set for a result cache hit query gets
slower as more rows are fetched. For fetching 10 row result set it took about
900ms but fetching 200 row result set took 8 seconds.
Reason for this slowness is GetOperationStatus is invoked inside
resultset.next() and it happens for every row even after operation has
completed. This is one RPC call per row fetched.
