Re: Hive Server 1.2 to Hive Server 2.0

Hi @Shihab

Hive 2.0 is in tech preview for HDP 2.5. The performance gain is due to LLAP which leverages persistent, distributed cache.

You enable LLAP by setting the Interactive query setting to "Yes" under the Hive config settings. This will setup an additional HiveServer 2 instance. You can run both Hive 1.2 and 2.0 on the same instance.


Please try it out. We'd love to hear your feedback.
