Bogdan DRAGU commented on HBASE-2393:
-------------------------------------
@Ryan
Yes. The patch ensures that the HTable constructor is called at most 100 times
(thus avoiding all the RPC in every single call) . All subsequent calls will
re-use the already created HTable instances stored in the mapping.
> ThriftServer instantiates a new HTable per request

> Every request creates a new HTable in ThriftServer, this is highly
> inefficient. It's even worse now that the HTable constructor does a RPC to
> the master.
> Assigning to Cosmin since he said they have some code they can share.
