Steve Loughran commented on YARN-4083:
--------------------------------------
+1 for some dynamicness, either the AM declares this or ZK does the heavy
lifting (the YARN registry can publish the info)
What's the security story here? That is: how do AM IP filters know when to
bounce an HTTP Request over to the proxy?

> Today many apps like Distributed Shell, REEF, etc rely on the fact that the
> HADOOP_CONF_DIR of the NM is on the classpath to discover the scheduler
> address. This JIRA proposes the addition of an explicit discovery mechanism
> for the scheduler address
