Description

If multiple clusters share a zookeeper cluster, users might use /rmstore/${yarn.resourcemanager.cluster-id} as the state store path. If user specified a customer value which is not a top-level path for ${yarn.resourcemanager.zk-state-store.parent-path}, yarn should create parent path first.
