Bug: _mlt on a document does not route properly on node clients

Elastic Stack Elasticsearch
1

I think I've found a bug with ElasticSearch with _mlt and node clients.

We're running 0.19.8.

We have two data nodes and each app server has its own ES instance running
in node client mode. Searches and normal document GETs work fine, however
when running _mlt on a client node, I get an IndexMissingException. The
exact same query works fine on the data node. I suspect _mlt is only
checking the local _mlt

To sum it up:

On data node:
$ curl http://localhost:9200/foo/bar/1 # Works
$ curl http://localhost:9200/foo/bar/1/_mlt # Works

On client node:
$ curl http://localhost:9200/foo/bar/1 # Works
$ curl http://localhost:9200/foo/bar/1/_mlt # Fails with
IndexMissingException

So just to clarify, the client nodes are joined correctly in the cluster,
so search works perfectly fine as well.

My colleague has raised an
issue: IndexMissingException when calling _mlt on client node · Issue #2197 · elastic/elasticsearch · GitHub
