Anoop Sam John commented on HBASE-4210:
---------------------------------------

Thanks [~lhofhansl] for the review.  I will address the comments from Ram and 
give updated patch.(Adding test cases)
bq.Also this won't allow the RegionObserver to interfere with the batch of 
operations (for example removing one)
May be CP can set the status so that region can ignore the Mutation?
                
> Allow coprocessor to interact with batches per region sent from a client(?)

> Currently the coprocessor write hooks - {pre|post}{Put|Delete} - are strictly 
> one row|cell operations.
> It might be a good idea to allow a coprocessor to deal with batches of puts 
> and deletes as they arrive from the client.
