@slfan1989 Thanks for your reply. The major idea is that follower sub-clusters are considerred as backup clusters, we don't use them until leader subcluster not working at all. hdfs has HA state and replications and ensure disaster tolerance within cluster. We're using this mode to make cross-cluster disaster tolerance work, so clients don't have to wait until the major cluster recovering, which takes long time. So basically this mode is not about using RBF to share overloading, but implement some kind of crosss-cluster disaster tolerance. -- This is an automated message from the Apache Git Service.
