> HDFS deployments can currently use the {{RequestHedgingProxyProvider}} to improve Namenode
failover detection in the client. It does this by concurrently trying all namenodes and picks
the namenode that returns the fastest with a successful response as the active node.
> It would be useful to have a similar ProxyProvider for the Yarn RM (it can possibly be
done by converging some the class hierarchies to use the same ProxyProvider)
> This would especially be useful for large YARN deployments with multiple standby RMs
where clients will be able to pick the active RM without having to traverse a list of configured
RMs.
