Issue with transport client and sniffing nodes


(Vesna Velichkovich) #1

Elasticsearch versio 6.2.4

I have few issues, most likely related.

  1. If I enable sniffing Transport client, it doesn't see any nodes and trying to use it, in specific example, getting all indices from cluster, results in error:
    NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{IK6R6eFjTk-wLEbJXIBE4A}{localhost}{127.0.0.1:9300}] ] at org.elasticsearch.client.transport.TransportClientNodesService.ensureNodesAreAvailable(TransportClientNodesService.java:347)

But, when I remove sniffing from settings, then I can see my client nodeServices.nodes list has my node.
When analyzing client in debugger, I can see that there is an issue in client.injector "Method threw 'java.lang.StackOverflowError' exception. Cannot evaluate org.elasticsearch.common.inject.InjectorImpl.toString()", but that doesn't stop client of creating new index when I tried that.
Not sure if this error is what causes issue number 2.

  1. Because if above, I commented out sniffing settings, just to see how far I will get, and trying to get all indices from cluster:

client.admin().
cluster().
prepareState().
execute().
actionGet().
getState().
getMetaData().
getIndices();

Well, that fails:

(Vesna Velichkovich) #2

Note: my transport client and nodes are same version (since I just read that can cause issues)


(Vesna Velichkovich) #3

I have xpack on cluster. maybe something with machine learning node or some node settings?


(Vesna Velichkovich) #4

Ok, when I use PreBuiltXPackTransportClient - then I resolved issue with response deserializing.

But I still have issue when I enable sniffing nodes (note: I have only one node on cluster, it was created for test) - I get NoNodeAvailableException. If I comment that setting out, all works.
