Description

Consider we have two clusters in A and S state, and then we transit A to DA. And later we want to transit DA to A, since the remote cluster is in S, we should be able to do it. But there are some remote wals on the HDFS for the cluster in S state, so we need to remove them first before transiting the cluster in DA state to A.
