Wenjun Zhu resolved HBASE-25789.
--------------------------------
Resolution: Not A Problem
> Other protobuf services, other than ClientService, cannot be invoked with
> RpcClient
> -----------------------------------------------------------------------------------
>
> Key: HBASE-25789
> URL: https://issues.apache.org/jira/browse/HBASE-25789
> Project: HBase
> Issue Type: Bug
> Components: native-client
> Affects Versions: 2.4.2
> Reporter: Wenjun Zhu
> Priority: Major
>
> I'd like to invoke a coprocessor with RpcClient, and I find the service_name
> in function RpcSerde::Header() has been hard coded, and when I change the
> service_name to another one, the call failed.
> Before I change the service_name, I get the following error message:
> {noformat}
> # ./adamas-echo-test
> /usr/src/hbase/hbase-native-client/src/test/adamas-echo-test.cc:83: Failure
> Failed
> Failed because: N5hbase15RemoteExceptionE: /172.17.0.4:16000 is unable to
> read call parameter from client 172.17.0.4;
> java.lang.UnsupportedOperationException: adamasEcho,
> Shouldn't get here, exception is not expected for RPC adamasEcho.{noformat}
> As I look into the hbase server, I find the service name is ClientService,
> which is not what I expected.
> then I hard code the "ClientService" to my own service, i.e. the service name
> in my own .proto file, by changing the INTERFACE macro.
> but when I connect to the hbase server, it reset the connection immediately,
> showing:
> {noformat}
> # ./adamas-echo-test
> /usr/src/hbase/hbase-native-client/src/test/adamas-echo-test.cc:83: Failure
> Failed
> Failed because: N5hbase11IOExceptionE: Connection closed to
> server:172.17.0.4:16000,
> Shouldn't get here, exception is not expected for RPC adamasEcho.{noformat}
> and I look into the wingle library, I find the errno is 104, which means
> 'Connection reset by peer'.
> So what is the problem?
> Thank you!
