Íñigo Goiri commented on HDFS-14215:
------------------------------------
Thanks for [^HDFS-14215-HDFS-13891-03.patch]. Minor nits:
* Check {{isEmpty()}} instead of {{size() == 0}}.
* Extract the first element of the iterator for readability.
> RBF: GetServerDefaults and GetStoragePolicies are dependent on Availability
> of Default NS
