> There are 3 RPC calls to fetch the same values :
> {code:java}
>   public FsStatus getDiskStatus() throws IOException {
>     return new FsStatus(getStateByIndex(0),
>         getStateByIndex(1), getStateByIndex(2));
>   }
> {code}
> {{getStateByIndex()}} is called thrice, which is actually a {{getStats}} RPC 
> to namenode, The same could have been achieved by just one call
