Elastic Search URI /_cluster/nodes not accessible
The _cluster/nodes endpoint has been removed in #4055, which is why your call returns an error. The change was released with elasticsearch 1.0.0.RC1. You can use the simplified _nodes endpoint instead now.
The error message you are getting:
No handler found for uri [/_cluster/nodes] and method [GET]
means that the url you are hitting is incorrect. Not exactly certain what you are trying to do, but I suspect you are trying to hit one of these two REST apis:
http://localhost:9200/_nodes/statshttp://localhost:9200/_nodesThis page in the Elasticsearch documentation list the cluster related REST api endpoints (includes the two above):
