Carter commented on HBASE-11825:
--------------------------------

Mikhail, I think this one is fairly high level so should have too much impact on internal interface details.

On a separate note, I'm adding [~sduskis] to this issue, who is going to take a stab at the patch with me.

> This is further cleanup of the HBase interface for 1.0 after implementing the new Table and Admin interfaces.  Following Enis's guidelines in HBASE-10602, this JIRA will generate a new ConnectionManager to replace HCM and Connection to replace HConnection.
> For more detail, this JIRA intends to implement this portion:
> {code}
> interface Connection extends Closeable{
>   Table getTable(), and rest of HConnection methods 
>   getAdmin()
>   // no deprecated methods (cache related etc)
> }
> @Deprecated
> interface HConnection extends Connection {
>   @Deprecated
>   HTableInterface getTable()
>   // users are encouraged to use Connection
> }
> class ConnectionManager {
>   createConnection(Configuration) // not sure whether we want a static factory method to create connections or a ctor
> }
> @Deprecated
> class HCM extends ConnectionManager {
>   // users are encouraged to use ConnectionManager
> }
> {code}
