> 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));
> }

> {{getStateByIndex()}} is called thrice, which is actually a {{getStats}} RPC
> to namenode, The same could have been achieved by just one call
