------------------------------------------------

Regarding HBaseAdmin, atleast in 0.94 we don't have an interface for that.  
Hence subclassing HBaseAdmin would help to define a wrapper around the core 
admin functionalities that we need.
Wrt HTable, we can implement the HTableInterface(or even extend the 
HTableInterface), but code in the MR side like TableInputFormatBase return 
HTable for APIs like getHTable().
So in these places if we need the wrapper of the HTable to be returned then 
need to change the MR code.  
If we are ok, then would change the MR code. Thoughts!!

> Allow subclassing of HTable and HBaseAdmin

> To extend functionality of HTable and HBaseAdmin we may need to subclass 
> them. This JIRA allows to add a default constructor and probably remove the 
> final variables in them so that we could subclass them.
