restarting NameNode

Harsh J commented on HDFS-3552:
-------------------------------
IIRC, the need was to change the policy at runtime if the environment/situation demanded so, instead of going through a restart.

> Pluggable placement policy was introduced into 0.21 as HDFS-385, but it would be more useful if user could change the placement policy without restarting NameNode.
