Closed indices have closed stores and thus access to IndexWriter fails with AlreadyClosedException while fetching ReplicationCheckpoint. One alternative here is read the replication checkpoint using DirectoryReader passing in the shard path.

Use case

Cluster manager fetches shard state of replicas via TransportNodesListGatewayStartedShards to fetch ReplicationCheckpoint. This checkpoint is then used by cluster manager to select the node containing the highest checkpoint.
