------------------------------
cc [~elgoiri] , [~weichiu] , [~hexiaoqiao] :
Now , i push a draft patch without checking style, which i have used in our
cluster.
It may be used for the graceful trash function and reduce the trash namenode
RPC load to 50%.
I also include the router side draft code.
Sorry for my so draft code. I can improve it when i am free.
> Add new trash rpc which move the trash (mkdir and the rename) operation to
> the server side.

> is not graceful。
> If we can move the client side trash (mkdir and rename) to the server side,
> we can not only solve the problem gracefully, but also reduce the trash rpc
> load in server side to about %50 compare to the origin trash which call two
> times rpc(mkdir and rename).
