Root URI Status

Elastic Stack Elasticsearch
1

Could someone clarify the difference between the 'status' field on the root
URL vs the 'status' field on /_cluster/health? In this system, the root
URL returns '200' even though the cluster is in 'yellow' as reported by the
cluster health check. What does 200 mean here? What are other possible
values?

~$ curl localhost:9200/_cluster/health?pretty=true
{
"cluster_name" : "elasticsearch",
"status" : "yellow",
"timed_out" : false,
"number_of_nodes" : 1,
"number_of_data_nodes" : 1,
"active_primary_shards" : 25,
"active_shards" : 25,
"relocating_shards" : 0,
"initializing_shards" : 0,
"unassigned_shards" : 25
}

~$ curl localhost:9200/
{
"status" : 200,
"name" : "elk1",
"cluster_name" : "elasticsearch",
"version" : {
"number" : "1.4.1",
"build_hash" : "89d3241d670db65f994242c8e8383b169779e2d4",
"build_timestamp" : "2014-11-26T15:49:29Z",
"build_snapshot" : false,
"lucene_version" : "4.10.2"
},
"tagline" : "You Know, for Search"
}

The value “200” to me is http response code. You can find other value if
your node can’t join the cluster, 503 in such case.

Cheers!

Actually as we are also providing this http response code within http response itself, it does not really make sense to keep it in the JSON response.
It will be removed in elasticsearch 2.0. PR coming here: Remove `status` code from main action `/` by dadoonet · Pull Request #8865 · elastic/elasticsearch · GitHub https://github.com/elasticsearch/elasticsearch/pull/8865
