> Hi,
> According to JDBC document, the driver setFetchSize(0) should ignore, but
> Hive JDBC driver returns no result.
> Our product uses setFetchSize to fine tune performance, sometimes we would
> like to leave setFetchSize(0) up to the driver to make best guess of the
> fetch size.
> Thanks
> Son Nguyen
