> REST invocations transparently to multiple RMs
> I think we need add a new Web Protocol for Router, like is
> {code:java}
> public interface RouterWebServiceProtocol extends RMWebServiceProtocol {
> List<ClusterInfo> getAllSubClusterInfo();
> ClusterInfo getSubClusterInfo(clusterId);
> SchedulerInfoType getSchedulerInfo(subClusterId);
> }
> {code}
> cause the Router needed some protocol, such is getAllSubClusterInfo():
> List<ClusterInfo> 、 getSubClusterInfo(clusterId): ClusterInfo
> 、getSchedulerInfo(subClusterId): SchedulerInfo 。 if needed i can do it.
