To your prePut() method you are getting an ObserverContext argument.
>From this you can easily get a ref to the current region.
Directly make calls to this region object. Creation of the HTable instance
and making a get() will be too much unwanted overhead.

Subject: connect to the region from coprocessor
In my preput coprocessor I would like to get the old value of the row been
input. Now I am creating a HTable instance and using the get interface;
function wise it works fine. Given the row is physically in the same
region as the cp, is there any lightweight approach doing that?
