James Taylor commented on PHOENIX-2743:
---------------------------------------

[~mini666] - with our 4.7 release, the validation check done by MutationState 
is only done once per call to commit. You can also prevent the RPC we do to 
check if the client has the current metadata through the UPDATE_CACHE_FREQUENCY 
property (see https://phoenix.apache.org/language/index.html#options). Please 
let me know if there's still an issue with 4.7.0 release - otherwise let's come 
up with some other solution to prevents having to change MutationState.

> 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.
> https://github.com/mini666/hive-phoenix-handler
> please, review my proposal.
