> When Raft group directory(DN Pipeline) is missing in a datanode on start up, the Raft server is not aware of the DN being part of a pipeline. Containers in OPEN/CLOSING state belonging to such containers should be moved UNHEALTHY state in such scenarios instead of CLOSED or QUASI_CLOSED state. QUASI_CLOSED state means that the DN raft server has applied all the transactions in it's raft log, but in this case since the DN doesn't apply raft log, all container replica corresponding to the pipeline is unhealthy it might not have all the transactions flushed.
