> if replication is driven from SCM side wouldnt it be easier to avoid for new DN -> old DN replication during the upgrade time? No. There is already a lot of criteria in place to select a new replica, including rack placement, capacity, and current load. We should avoid adding any new restrictions that may inhibit operations that restore durability. This would be especially restrictive because it would last indefinitely (there is no upper bound on time admins take to upgrade DN software or the finalization time after that) and eliminate the majority of datanodes as replication targets in many cases. -- This is an automated message from the Apache Git Service.
