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.
