Anoop Sam John commented on HBASE-16769:
----------------------------------------

For getting the edits/cells which are getting replicated, there are ways..  
Even the CP hooks around pre/post put/delete/batchMutate will get called..  
The use of this particular CP hook (preReplicateLogEntries) is in 
AccessController.   ACL was missing for the replicate APIs and that jira added 
this new hook.  For that , there is no need for these edits any way.. Still as 
a general way, we passed them.  Now just to call the CP we should not be making 
POJOs from PB objects.  So we will need these hooks until our ACL works with CP 
impl way. There is no other go.

> Deprecate/remove PB references from MasterObserver and RegionServerObserver
