Andrew Wang commented on HADOOP-14104:
--------------------------------------
Hi Yongjun, what you describe is how the existing KMS HA already works.
One thing I might recommend is that we don't query getServerDefaults after we
get the KP initially. This way we don't need to worry about the value changing
later (or an exception being thrown).
> Client should always ask namenode for kms provider path.

> According to current implementation of kms provider in client conf, there can
> only be one kms.
> 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.
