Problem description

There is no way to acquire failed nodes field (/_nodes/failed) from query result. Query result:

{
  "_nodes": {
    "total": 2,
    "successful": 1,
    "failed": 1
  },
  "cluster_name": "swamp",
  "nodes": {}
}

Hello! Getting the failed nodes should be:

esClient.nodes().stats().nodeStats().failed();

or did you mean something else? let me know :)
