Binglin Chang updated HADOOP-8985:
----------------------------------
Description:
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?
