Aaron T. Myers commented on MAPREDUCE-4344:
-------------------------------------------

You might also take a look at the ZK stuff (which includes support for authentication and authorization) that was added to support the ZK Failover Controller for HA HDFS. Perhaps some of this can be refactored?

> ZKClient class in YARN, currently unused (but still induces a dependency, but thats another discussion) has the following comment:
> {code}
> /** ZK Registration Library
>  * currently does not use any authorization
>  */
> {code}
> We ought to have auth support in it if its to be kept around and used.
> This may also be related to MAPREDUCE-4343 in some ways.
