Xuan Gong commented on YARN-1611:
---------------------------------
The proposal :
To use it in HA, the client has to upload the new configuration file into
remote File System (such as hdfs) before we can load the new configs.
For example, if we call refreshQueues in HA, the client need to upload the
modified capacity-scheduler.xml into hdfs. When refreshQueues is called,
the capacity scheduler will reinitiate queues with this modified
capacity-scheduler.xml.
So, we will make a RemoteConfiguration class that extends Configuration, and
implement a FileSystemBasedRemoteConfiguration that has the FileSystem based
utility.
When HA is enable, instead of simply call getConfig(), we will enforce new
configs from the RemoteConfiguration.
> Make admin refresh* s work for both Active RM and Standby RM

> Currently, If we do refresh* for a standby RM, it will failover to the
> current active RM, and do the refresh* based on the local configuration file
> of the active RM.
