Wei Yan commented on HDFS-13224:
--------------------------------

Thanks for the patch, [~elgoiri]. Took a quick pass, and the entire design LGTM.

Have some questions here:
 * RouterRpcServer.isPathAll() function, currently it returns true if mount 
point is HASH_ALL. For some others like RANDOM, it should also return true, 
right?
 * For HashFirstResolver, do we also need to handle temorary naming pattern 
there?

One minor thing, in MultipleDestinationMountTableResolver.java, the javadoc "It 
has three options to order the locations:" should be updated to four.

> Currently, a mount point points to a single subcluster. We should be able to 
> spread files in a mount point across subclusters.
