> From [~stevel@apache.org],
> via YARN: 
> # AM provider needs to pass down the app ID for a lookup via YARN (will need relevant tokens to access YARN for lookups)
> # Agent enums all apps, finds one with relevant app
> # from the AppRecord extracts the unmodified URL path
> # Issue: how often to refresh value? On every heartbeat? or after a connection refused?
> via ZK
> # AM/provider registers with ZK
> # provider passes down path to agent
> # agent does a ZK refresh
> # client code can use the same mechanism
