JeongMin Ju commented on PHOENIX-2743:
--------------------------------------

Thange for reply.
The change of MutationState is to disable validation check for batch upsert.
The current code of MutationState.validate is very inefficient because of 
checking every row.
If turn off the validation when batch upsert. Performance is improved.

> Phoenix support hash join & sort-merge join. But in case of big*big join does 
> not process well.
> Therefore Need other method like Hive.
> I implemented hive-phoenix-handler that can access Apache Phoenix table on 
> HBase using HiveQL.
> hive-phoenix-handler is very faster than hive-hbase-handler because of 
> applying predicate push down.
> I am publishing source code to github for contribution and maybe will be 
> completed by next week.

> please, review my proposal.
