Anoop Sam John commented on HBASE-4210:
---------------------------------------
bq.Todd introduced initialized variable so that we don't call preXXX hooks more
than once
Yes Ted I am aware of this change that had happened. But all the pre hooks for
each of the Mutation will be called at 1st step itself. After that the actual
mutate operation might be happening in N batches.
We would like to have a pre/post hooks for each of the mini batch mutation.(One
call for each mini operation)
May be it would be better to have one pre/post hook for the entire batch
operation also? -> As per our use case we wanted a such a hook also.
> Allow coprocessor to interact with batches per region sent from a client(?)

> Currently the coprocessor write hooks - {pre|post}{Put|Delete} - are strictly

> It might be a good idea to allow a coprocessor to deal with batches of puts
