[jira] [Created] (HADOOP-9606) Protocol buffer support cannot compile under C

Ralph Castain created HADOOP-9606:
-------------------------------------

             Summary: Protocol buffer support cannot compile under C
                 Key: HADOOP-9606
                 URL: https://issues.apache.org/jira/browse/HADOOP-9606
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 2.0.4-alpha
            Reporter: Ralph Castain


When compiling Hadoop's .proto descriptions for use in C, an error occurs because one of the RPC's in NamenodeProtocol.proto is named "register". This name is a reserved word in languages such as C. When using the Java and C++ languages, the name is hidden inside a class and therefore doesn't cause an error. Unfortunately, that is not the case in non-class languages such as C.

Note: generating the C translation of the .proto files requires installation of the protobuf-c package from google:
