Hbase Connection Pool 1.0.0

Question

Since the Hbase 1.0+ API does not process the connection pool using HConnectionI want to know what are the best methods for creating a connection pool?

So far I have created an object Connectionlike ThreadLocal, but I'm not sure if this is a good idea.

In general, since the connection object is so heavy, is it useful to create a connection pool?

Does anyone have any ideas?
