Xuan Gong commented on YARN-1482:
---------------------------------
as I describe on previous comment, the webapoproxy will keep looping if there
is no active rm. It will not keep doing it forever. Either it will find the
active rm or it will crash because of timeout.
About how long it will keep looping until the timeout happens is based on
configurations that we set up for failover (such as max-attempts, etc).
> WebApplicationProxy should be always-on w.r.t HA even if it is embedded in
> the RM

> This way, even if an RM goes to standby mode, we can affect a redirect to the
> active. And more importantly, users will not suddenly see all their links
> stop working.
