Andrew Wang commented on HADOOP-14104:
--------------------------------------
I think a full YARN job is a bit much; basically I wanted a unit test that did
an encrypted read/write using the KP URI from the credentials.
This might be partially addressed by an existing HDFS encryption test, but I'd
like to see the same verification as in the newly added unit tests that the
value from the credentials overrides the value in the config.
> 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.
