Lars Hofhansl commented on HBASE-11733:
---------------------------------------
bq. execOperation(coprocessors.isEmpty() ? null : new CoprocessorOperation()
+1 on that. Normally this would not even be an issue except for tight loop
hooks that hook into scanner.next(), etc.
+1 on committing with this check in place.
> Avoid copy-paste in Master/Region CoprocessorHost
