> Key: HADOOP-8985
> URL: https://issues.apache.org/jira/browse/HADOOP-8985
> Project: Hadoop Common
> Issue Type: Improvement
> Components: ha, ipc
> Affects Versions: 2.0.2-alpha
> Reporter: Binglin Chang
> Assignee: Binglin Chang
> Priority: Minor
> Fix For: 3.0.0, 2.0.3-alpha
>
> Attachments: HADOOP-8985-add-namespace.patch
>
>
> Currently .proto files use java_package to specify java packages in proto
> files, but namespace are not specified for other languages such as cpp, this
> causes name collision in cpp. 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 cpp) for
> all common sub-project proto files, and "hadoop.hdfs"(hadoop::hdfs in cpp)
> for all hdfs sub-project proto files?
