With a standard LB in front of an N-node cluster, what's the best URL in
the ES API to check the health of a particular node (so as to know to
remove it at least temporarily).
There is the node info API:
curl -XGET 'http://localhost:9200/_nodes'
But that's returning node info for all the nodes in the cluster that
localhost is a member of. I want something like /_nodes/_current. Or
maybe the fact that a particular node can even process any GET request
(e.g., http://localhost:9200/_cluster/health) signifies that it is
responsive enough and can take requests?
