Hi,
I want to know the node unique ID for an elasticsearch node via an API.
There is
[https://www.elastic.co/guide/en/elasticsearch/reference/1.3/cat-nodes.html](https://www.elastic.co/guide/en/elasticsearch/reference/1.3/cat-nodes.html)
but it only shows a four letter abbreviated ID. I need the full ID so I can
parse the output of
[https://www.elastic.co/guide/en/elasticsearch/reference/1.5/cluster-nodes-stats.html](https://www.elastic.co/guide/en/elasticsearch/reference/1.5/cluster-nodes-stats.html)
which requires prior knowledge of node ID.
Please help.

Hi,
You can use `full_id` parameter with \_cat API.
"GET \_cat/nodes?v&full\_id=true&h=id"
