Nicolas Liochon commented on HBASE-9117:
----------------------------------------
bq. the createConnections have a corresponding close?
Yes. Creating/Closing a connection is supposed to be expensive. It holds a
connection to ZooKeeper, the region cache, this kind of stuff. I will need to
look at the patch in details, but I'm not sure this part have been removed.
> Remove HTablePool and all HConnection pooling related APIs
