Subject [jira] [Created] (HADOOP-8985) Add namespace declarations in .proto files for other languages
Date Fri, 26 Oct 2012 05:55:12 GMT
Binglin Chang created HADOOP-8985:

             Summary: Add namespace declarations in .proto files for other languages
                 Key: HADOOP-8985
                 URL: https://issues.apache.org/jira/browse/HADOOP-8985
             Project: Hadoop Common
          Issue Type: Improvement
            Reporter: Binglin Chang
            Priority: Minor

Currently .proto files use java_package to specify java packages in proto files, but namespace
are not specified for other languages such as C++, this causes name collision in C++. we can
add namespace declarations to avoid this. 

In Java, the package specifier is used as the Java package, unless you explicitly provide
a option java_package in your .proto file. So the original java package will not be affected.

About namespace name, how about "hadoop.common"(hadoop::common in C++) for all common sub-project
proto files, and "hadoop.hdfs"(hadoop::hdfs in C++) for all hdfs sub-project proto files?
