Index shard stats for the follower shard are fetched, when a shard follow task is started. This is needed in order to bootstap the shard follow task with the follower global checkpoint. Sometimes index shard stats are not available (e.g. during a restart) and we fail now, while it is very likely that these stats will be available some time later.

There was a problem hiding this comment.
Oh, actually, one comment; can you leave a comment here about this, since it's slightly different retry logic from elsewhere.
…dException if the index exists in local cluster state and a IndexNotFoundException if it no longer exists. This way we can complete rely on ShardFollowNodeTask.shouldRetry(...)
