In case an error is returned when calling search_shards on a remote cluster, which will lead to throwing an exception in the coordinating node, we should make sure that the status code returned by the coordinating node is the same as the one returned by the remote cluster. Up until now a 500 - Internal Server Error was always returned. This commit changes this behaviour so that for instance if an index is not found, which causes an 404, a 404 is also returned by the coordinating node to the client. Closes elastic#27461

There was a problem hiding this comment.
RemoteTransportException implements ElasticsearchWrapperException, then unwrapCause will unwrap the inner cause and status() will return the inner status see https://github.com/elastic/elasticsearch/blob/master/server/src/main/java/org/elasticsearch/ElasticsearchException.java#L235
This behaviour is tricky. I think how ElasticsearchException#status works may cause problems when for instance it is thrown in the high-level REST client, I will have to dig deeper on that and probably open a follow-up PR, but I think this change is enough for cross-cluster search.
