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. http://hortonworks.com/blog/llap-enables-sub-second-sql-hadoop/

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.
