>                 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.
