ON PROTOBUFS This maven module has protobuf definition files ('.protos') used by hbase Coprocessor Endpoints that ship with hbase core including tests. Coprocessor Endpoints are meant to be standalone, independent code not reliant on hbase internals. They define their Service using protobuf. The protobuf version they use can be distinct from that used by HBase internally since HBase started shading its protobuf references. Endpoints have no access to the shaded protobuf hbase uses. They do have access to the content of hbase-protocol -- the .protos found in here -- but avoid using as much of this as you can as it is liable to change. Generation of java files from protobuf .proto files included here is done as part of the build.
