Konstantin Shvachko commented on HBASE-6340: -------------------------------------------- I also see that ProtobufRpcEngine.Invoker in HBASE-6414 correctly obtains the protocol version from the protocol itself rather than from the method as in current impl. So this should be compatible. > HBase RPC does not allow protocol extension with common interfaces. > ------------------------------------------------------------------- > > Key: HBASE-6340 > URL: https://issues.apache.org/jira/browse/HBASE-6340 > Project: HBase > Issue Type: Bug > Components: coprocessors, regionserver > Affects Versions: 0.92.0 > Reporter: Konstantin Shvachko > Assignee: Konstantin Shvachko > Attachments: RPCInvocation.patch > > > HBase RPC fails if MyProtocol extends an interface, which is not a > VersionedProtocol even if MyProtocol also directly extends VersionedProtocol. > The reason is that rpc Invocation uses Method.getDeclaringClass(), which > returns the interface class rather than the class of MyProtocol. -- This message is automatically generated by JIRA.
