No data node with id found

[larghir]

Hi,
I'm getting this error when trying to connect to a remote ES host:

org.elasticsearch.hadoop.rest.EsHadoopInvalidRequest: ElasticsearchIllegalArgumentException[No data node with id[...] found

Same configuration for localhost works without problems.

• Am using version 2.2.0-m1
• ES version 1.7.1
• Node is reachable via HTTP

Any hints appreciated

Can you provide more information about the setup? The exception occurs if the data node is detected during discovery but the connector cannot reach it - maybe the IP is incorrect (private vs public) - typically occurs in cloud environments.

Downgraded to version 2.1.1 and it works.

Okay. Can you please enable logging in 2.2.0-m1 on the rest package and post the log as gist? It would be useful to understand what is going on?

Thanks,

Unfortunately there's no relevant information - the rest package should be set on TRACE level to see the actual replies from the cluster (and thus why the data node is not found in 2.2.m1 vs 2.1.1).

I can't read anything from the trace logs either but there it is

Thanks - that's much better. Looks like there's an error in the generated QueryDSL.
I'll keep you posted.

P.S. Thanks for your patience in getting the logs.

[larghir]

:) Sure. Thanks also

[costin]

By the way, would you please post a gist with the logs from es-connector 2.1.1? Thanks!

@larghir Something's a miss. Would you mind turning TRACE on the entire org.elasticsearch.hadoop and org.elasticsearch.spark packages and upload the logs as a gist again?
If possible, can you please join the #elasticsearch IRC channel - I'm using the same user as on github.

It looks like you are running ES both locally and on a remote cluster and for some reason, the connector falls back to the local cluster which clearly doesn't have the same node as the remote one.

Hi again, don't seem to find you on the IRC channel. Indeed I am using two ES configurations for two ES clusters, one of them is local. I will try to get the logs soon (I assume you want those from 2.2.0-m1)
