What is equivalent of impala in hortonworks?

Hi there,

I just like to know, what is equivalent of impala(from CDH) in Hortonworks. How to achieve better query performance in Hortonworks instead of using Hive. I would appreciate if anyone provide some information on this.

Thanks & Regards,

Jee

HDP 2.5 has a technical preview for LLAP .LLAP is a caching layer on top of yarn, which allows improved hive query performance. You can enable LLAP from ambari hive config page.

Hi Karthick Narayanan,

Thank you very much for your prompt reply and it will be really helpful. Once again, Thank you.

Here is a very good blog showing a performance comparison of Hive LLAP to Impala. It uses 10TB of TPC-DS Data Warehouse data to get a solid apples-to-apple comparison of the two. http://hortonworks.com/blog/apache-hive-vs-apache-impala-query-performance-comparison/
