Ralph Castain commented on HADOOP-9606:
---
Details of the error when executing the protobuf-c parser on
NamenodeProtocol.proto:
protoc-c --c_out=. -I . -I NamenodeProtocol.proto
The "register" function appears on line 714 of the resulting
NamenodeProtocol.pb-c.h file:
{code}
void (*register)(Hadoop__Hdfs__NamenodeProtocolService_Service *service,
const Hadoop__Hdfs__RegisterRequestProto *input,
Hadoop__Hdfs__RegisterResponseProto_Closure closure,
void *closure_data);
{code}
It's a direct consequence of line 228 in the .proto file:
{code}
/*
* Request to register a sub-ordinate namenode
*/
rpc register(RegisterRequestProto) returns(RegisterResponseProto);
{code}
The rpc needs to be renamed to something non-reserved.
