> For Ratis Replication, on a Healthy DN, we have a existing container to export as a tarball, then other DNs come to read them and then import locally. > For EC Offline Recovery, on a CoordinatorDN, we'll have several container replicas on disk **with the same containerID**, so we can't have them all in a normal place as Ratis Replication, then we can't reuse the `exportContainer` API easily Thanks @guihecheng for pointing out the issue. There is one more problem: For Ratis replicas, each DN in the pipeline should persist the same container. For EC, CoordinatorDN should not persist the recovered containers that does not belong to it. Unless we allow a degraded state in which some of the DN may hold more than one container in a container group. -- This is an automated message from the Apache Git Service.
