The class HiveResultSet should implement batch fetching.

Key: HIVE-1815
URL: https://issues.apache.org/jira/browse/HIVE-1815
Project: Hive
Issue Type: Improvement
Components: Drivers
Affects Versions: 0.5.0
Environment: Custom Java application using the Hive JDBC driver to
connect to a Hive server, execute a Hive query and process the results.
Reporter: Guy le Mar
When using the Hive JDBC driver, you can execute a Hive query and obtain a
HiveResultSet instance that contains the results of the query.
Unfortunately, HiveResultSet can then only fetch a single row of these results
from the Hive server at a time. As a consequence, it's extremely slow to fetch
a resultset of anything other than a trivial size.
It would be nice for the HiveResultSet to be able to fetch N rows from the
server at a time, so that performance is suitable to support applications that
provide human interaction.
(From memory, I think it took me around 20 minutes to fetch 4000 rows.)
