Ayush Saxena commented on HDFS-15096:
-------------------------------------

Thanx [~elgoiri]  for the review.
What should I verify in the test? Should I call getServerDefaults() multiple 
times? 
Since it is just caching, so output would be same only.

> Presently each getServerDefault calls are triggered to the Namespace, The 
> DFSClient caches the getServerDefaults(), similarly the Router can also cache 
> the getServerDefaults(), as router connects to multiple clients, this 
> improves performance for subsequent calls.
