"No ElasticSearch Node Available"

[nicolaifsf]

Please use the following questions as a guideline to help me answer
your issue/question without further inquiry. Thank you.

Which version of Elastic are you using?

[ ] elastic.v2 (for Elasticsearch 1.x)
[x ] elastic.v3 (for Elasticsearch 2.x)

Please describe the expected behavior

NewClient(elastic.SetURL("http://:9200")
would correctly generate a new Client object connecting to the node

Please describe the actual behavior

"no ElasticSearch node available"

Any steps to reproduce the behavior?

elastic.NewClient(elastic.SetURL("http://:9200")

Does it work with "http://127.0.0.1:9200"?

[olivere]

What does curl 'http://:9200/_nodes/http?pretty' return? Because Elastic uses a process called Sniffing to determine the other nodes of the cluster. Maybe they're unavailable?

[olivere]

Please respond to the issue if the question remains. Otherwise I'll close the issue. Thank you.

[nicolaifsf]

I apologize for the delay. I made a mistake in formatting the markdown here.
The issue is when I do something like elastic.NewClient(elastic.SetURL("http://someaddresshere:9200"))
A curl to that address works just fine, however it tells me that no elastic search node is available still.
Thank you for your prompt responses and well maintaining of this repo.

Can you please try what I wrote in the 2nd comment?

[nicolaifsf]

elastic.NewClient(elastic.SetURL("http://127.0.0.1:9200")) works

[olivere]

What does curl 'http://:9200/_nodes/http?pretty' return?

I ended up using SimpleClient and it worked, however I just thought I should let you know that I was having some issues with NewClient. Are there any major differences between the two that could have been the root cause?

[olivere]

SimpleClient simply disables a few things like automatically finding new nodes added to your cluster by the Sniffing procedure I linked to above. You can disable sniffing via options in NewClient, as described in the Wiki.

Not sure what's wrong with your setup. Cluster output is looking good, sniffing should pick up the setting in http_address.

[nicolaifsf]

Ah well, thanks for your help!

I have the same issue, directly using CURL to my node on localhost works, including the _nodes call mentioned above.

I use SetSniffer(false) and it all started working. What information can I provide that would help with debugging?

[olivere]

This problem is most probably due to Elastic picking up the address returned by Nodes API, which simply isn't routable. This is e.g. the case for ES running inside a Docker container. Does it work with sniffing disabled? Refer to the wiki for details.

What is the output from the Nodes API call mentioned earlier?
