Arun Suresh commented on HADOOP-11620:
--------------------------------------

hi [~lmccay], thanks for taking a look at the patch,
The new scheme is only meant to be understood by the 
{{KMSClientProvider#Factory}} to instantiate a the new Loadbalancing 
KMSClientProvider. One is still free to use the existing 
{{hadoop.security.key.provider.path}} to designate multiple providers. Also, I 
was not really looking to create multiple providers.. The point of the patch is 
to create a single provider that load balances across hosts. 

> Add Support for Load Balancing across a group of KMS servers for HA
