------------------------------------------
Hi [~shahrs87] thanks much for your patch. Looks good overall but I still have
a few questions.
{quote}
According to current implementation of kms provider in client conf, there can
only be one kms.
{quote}
This is not a precise statement though, considering that multiple kms instances
can be added for load balancing purposes. Would you mind to update the release
note once this patch gets committed?
Preferably also state (in the doc, maybe?) that this only works if both client
and namenodes are on a supported version, otherwise the client's local kms
config is used.
Can we also add a test to ensure clients can access files in an encrypted
remote cluster using the token obtained from the remote NameNode?
> Client should always ask namenode for kms provider path.

> In multi-cluster environment, if a client is reading encrypted data from
> multiple clusters it will only get kms token for local cluster.
> Not sure whether the target version is correct or not.
