Thanks Jorn for your interest and appreciate your helpful comments.
I am primarily interested in this case to make Hive work with Spark engine. It may well be that it is work in progress and we have to wait for it.

You may also wait for hive on tez with tez version >= 0.8 and hive > 1.2. Before that I recommend first trying other optimizations of Hive and have a look at the storage format together with storage indexes (not the regular ones), bloom filters, partitions etc Then, check the data model. A data model using only varchar is pretty useless. Afterwards check the execution engine (tez, spark, etc.). Most common Hadoop distribution should have at least spark preconfigured. Alternatively, if you do not deal with bulk analytics but more single inserts updates, deletes, you may want to use an external hbase table. Finally, you can check in-memory caches.

This is in contrast to install and configure Spark as an application. Spark by default uses MapReduce as its execution engine which is more for batch processing. The primary reason I want to use Hive on Spark engine is for performance.
