Chris Nauroth resolved HDFS-241.
--------------------------------
Resolution: Won't Fix
I'm going to close this. The idea of doing recursive operations on the server
side has come up in discussion on a few other things recently. The consensus
is that we're actually reliant on the client side to drive tree traversal as a
form of RPC throttling. (Server-side tree traversal would cause an individual
client to consume an RPC handler thread in the NameNode for a longer period of
time.) There is also the issue of cross-filesystem symlinks, which require
resolution on the client side in case there is a client-side mount table
configured or a symlink pointing to a different cluster.
