Wangda Tan commented on YARN-4971:
----------------------------------
I think we should revisit the patch based on comment from Karthik:
https://issues.apache.org/jira/browse/YARN-4971?focusedCommentId=15281097&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15281097
I also don't quite understand why the following methods of ClientRMService are
different:
One is:
{code:java}
InetSocketAddress getBindAddress(Configuration conf) {
return conf.getSocketAddr(
YarnConfiguration.RM_BIND_HOST,
YarnConfiguration.RM_ADDRESS,
YarnConfiguration.DEFAULT_RM_ADDRESS,
YarnConfiguration.DEFAULT_RM_PORT);
} {code}
And another one is:
{code:java}
clientBindAddress = conf.updateConnectAddr(YarnConfiguration.RM_BIND_HOST,
YarnConfiguration.RM_ADDRESS,
YarnConfiguration.DEFAULT_RM_ADDRESS,
server.getListenerAddress());{code}
Basically, in serviceInit and serviceStart, how to get RM address is different.
Is that a potential root cause of the problem? [~wilfreds], [~shuzirra]

>
> 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
