-----------------------------------------------
Thanks [~linyiqun] for review..
bq. Now I see there are some checkstyle and whitespace warnings generated,
would you have a clean up?
Checkstyle is related to method length and I think we no need to fix.
Whitespace I will remove in next patch..
I will wait for others review.
> Avoid unnecessary edit log for setStoragePolicy() and setReplication()

> We are setting the storage policy for file without checking the current
> policy of file for avoiding extra getStoragePolicy() rpc call. Currently
> namenode is not checking the current storage policy before setting new one
> and adding edit logs. I think if the old and new storage policy is same we
> can avoid set operation.
