Rushabh S Shah commented on HADOOP-14104:
-----------------------------------------

bq. Wonder if you have chance to look at Daryn's comments?
I was out last week and before that busy working on internal stuff.
I should be able to upload a new patch today.
bq. An actual mini-cluster test that mimics an MR job submitter and task's call 
pattern would also be good.
I was able to address all the review comments except the above one.
Only way I can think to mimic job submitter is by creating MiniYARNCluster. I 
don't have any experience writing yarn tests. I may take additional time if you 
want me to write miniyarn cluster test.
[~yzhangal], [~andrew.wang]: Any pointers would be appreciated.

> 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.
