Sean Busbey updated HBASE-13646:
--------------------------------
Resolution: Fixed
Hadoop Flags: Incompatible change
Release Note: When RegionServerCoprocessors throw an exception we will no
longer attempt to build an incomplete RPC response message. Instead, the
response message will be null.
Status: Resolved (was: Patch Available)
pushed to branch-1, branch-1.2, and 0.98.
Added a release note about the change for coprocessors; would appreciate a
quick review to make sure it's correct.
> HRegion#execService should not try to build incomplete messages

>
> If some RPC service, called on region throws exception, execService still
> tries to build Message. In case of complex messages with required fields it
> complicates service code because service need to pass fake protobuf objects,
> so they can be barely buildable.
> To mitigate that I propose to check that controller was failed and return
> null from call instead of failing with exception.
