I think splitting doesnt distribute your read load.
With read load distribution i mean you can access same data on let say 3
different nodes (RS) - if the dfs replication is set to 3. What Hbase doesnt
handle, am i right?

Hi,
I am currently looking at adding a transactional consistency aspect to HBase
