Koji Noguchi resolved HDFS-23.
------------------------------

    Resolution: Duplicate

I'm hoping HDFS-985 is our answer.
No more chasing down users hitting namenode with liststatus.

> We recently had couple of clusters go down due to users' tasks calling dfs -ls frequently
on a large directory.
