Ray Chiang commented on YARN-4971:
----------------------------------
+1 (nonbinding). The only new test I can think of would be to verify that the
member variable address stays at 0.0.0.0 if it's initially 0.0.0.0--mainly
useful as a "spec" for the class behavior.
> RM fails to re-bind to wildcard IP after failover in multi homed clusters

> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager

>
> If the RM has the {{yarn.resourcemanager.bind-host}} set to 0.0.0.0 the first
> time the service becomes active binding to the wildcard works as expected. If
> the service has transitioned from active to standby and then becomes active
> again after failovers the service only binds to one of the ip addresses.
> There is a difference between the services inside the RM: it only seem to
> happen for the services listening on ports: 8030 and 8032
