Hive and HBase can coexist independently on top of the same DFS filesystem and cluster. 

There are two ongoing projects to hook up HBase and HIVE that I am aware of:


Depending on how far along these, some level of cooperation can be possible. More certainly
down the road.

Subject: can Hive & HBase co-exist on the same cluster?

Hi all,
I am a newbie doing some research to put-together a system to process
large number of log-records.

A) Hbase system with clients executing MR jobs on the data

B) there may be some instances where we need to run ad-hoc queries on
the data.  I am trying to see if this can be done with out users
having to resort to writing MR programs.  HQL might be enough.  But if
it is not, I am considering Hive.

so that brings to my questions

1) Can both Hive and Hbase co-exist on the same cluster?

2) can they 'share' the same data/schema?  or do I need to insert the
same  data into Hbase table and Hive table?
