             Summary: Create endpoint coprocessors for write operations instead of piggybacking on region observer
                 Key: PHOENIX-3177
                 URL: https://issues.apache.org/jira/browse/PHOENIX-3177
             Project: Phoenix
          Issue Type: Bug
            Reporter: James Taylor


We too frequently piggyback on our UngroupedAggregateRegionObserver to do various write-oriented operations such as stats collection, upgrade utilities, delete operations, upsert/select operations, adding the empty key value, and maybe more I've missed.

We should either rename UngroupedAggregateRegionObserver to GrabBagRegionObserverOrWriter (smile) or we should create separate endpoint coprocessors for each operation.
