[jira] [Commented] (HBASE-25789) Other protobuf services, other than ClientService, cannot be invoked with RpcClient

["Wenjun Zhu (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-25789?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17333030#comment-17333030 ] 

Wenjun Zhu commented on HBASE-25789:
------------------------------------

well, I invoke the coprocessor I implemented through ExecService rpc in ClientService.

And I create a table through CreateTable rpc in MasterService.

 

So this is resolved.

> 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!
