> Creating new jira to track suggestions that came in review (https://reviews.apache.org/r/62141/)
but are not blocker and can be done separately.
> Suggestions by [~apurtell]
> -  Change {{Service Coprocessor#getService()}} to {{List<Service> Coprocessor#getServices()}}
> - I think we overstepped by offering [table resource management via this interface|https://github.com/apache/hbase/blob/master/hbase-client/src/main/java/org/apache/hadoop/hbase/CoprocessorEnvironment.java#L57].
There are a lot of other internal resource types which could/should be managed this way but
they are all left up to the implementor. Perhaps we should remove the table ref management
and leave it up to them as well.
> ----
> - Checkin the finalized design doc into repo (https://docs.google.com/document/d/1mPkM1CRRvBMZL4dBQzrus8obyvNnHhR5it2yyhiFXTg/edit)
(fyi: [~stack])
> - Added example to javadoc of Coprocessor base interface on how to implement one in the
new design
