Description

StoreScanner can be replaced by preStoreScannerOpen hook with CP. In order to reuse most of the logic in current StoreScanner, subclass it might be the best approaching. Thus a lot of private member need to be changed from private to protected.

At present, in order to to implement a custom storescanner for dot (HBASE-6805), only a few of the private member need to be changed as in the attached storescanner.patch, while should we change all the reasonable field from private to protected as in HBASE-7387-v?.patch
