Michael Stack b392de3e31 HBASE-17653 HBASE-17624 rsgroup synchronizations will (distributed) deadlock This patch restores the regime instituted in original rsgroups patch (HBASE-6721) where reading of rsgroup state runs unimpeded against COW immutable Maps whereas mutation to state require exclusive locks (updating the Maps of state when done). HBASE-17624 was over-enthusiastic with its locking down of access making it likely we'd deadlock. Adds documentation on concurrency expectations.		2017-02-17 14:45:56 -08:00

ON PROTOBUFS
This maven module has core protobuf definition files ('.protos') used by hbase
table gropuing Coprocessor Endpoints.

Generation of java files from protobuf .proto files included here is done apart
from the build. Run the generation whenever you make changes to the .orotos files
and then check in the produced java (The reasoning is that change is infrequent
so why pay the price of generating files anew on each build.

To generate java files from protos run:

 $ mvn compile -Dcompile-protobuf
or
 $ mvn compile -Pcompile-protobuf

After you've done the above, check it and then check in changes (or post a patch
on a JIRA with your definition file changes and the generated files). Be careful
to notice new files and files removed and do appropriate git rm/adds.
