Xuan Gong commented on YARN-1459:
---------------------------------
This patch is based on https://issues.apache.org/jira/browse/YARN-1611.
In YARN-1611, we create a common functionality to read remoteConfiguration.
Also, when we do the refresh*, it will automatically find the active rm, and do
the refresh* for this active rm.
In this patch, we have following:
* when RM goes to active, it will call all the refresh* to get the latest
configuration.
* Add idempotent annotation for all refresh* functions. In that case, they will
retry if failover happens.
> Handle supergroups, usergroups and ACLs across RMs during failover
