curl -s 'http://localhost:9200/_cat/nodes'
{"error":"NullPointerException[null]","status":500}

Nothing else is logged on the masters or data nodes.
We have Logstash 1.4.1 connected to the cluster, but this happens regardless of whether the Logstash nodes are connected or not.

I can't repro locally. Can you post /_cluster/state?filter_metadata and /_nodes?all somewhere?

or do you see a stacktrace in the logs somewhere?

Hi @drewr ew, I hope you don't mind, I emailed them to you as they contain data I'd prefer not to post publicly :)

@s1monw no stack traces from this in any logs on any ES node.

@avleen I don't mind at all. However, I haven't seen anything yet. Where did you send it? You can use first.last@elasticsearch.

Update: Nevermind, spam. 😈

Hi Drew,

Just double checked.. Yup that's where I sent it, at 17:29 ET.
Has two attachments, a zip file and a text file.

FWIW I'm also seeing this, on a freshly-updated 1.2.1 cluster (from 1.1.1) with 64-bit Java 1.7.0_55, CentOS 5.8.

This PR addresses should fix this NullPointerException:
#6190

The fix will be included in 1.2.2

Hi,
For info - just installed ES for the first time a week ago (1.2.1 debian wheezy 64bit), and hit this issue. Upgraded to 1.2.2 yesterday, and it still reports the NullPointerException when requesting _cat/nodes. Installed using the debian packages. Also get on a newly installed 1.2.2 node (though joined to the same cluster).
Cheers,
Matthew

Any stack trace in nodes logs?

No, nothing in node logs. Is there any way to increase debugging, maybe? I wondered if the package hadn't upgraded correctly, but it's all reporting 1.2.2 (logs say version[1.2.2], pid[10140], build[9902f08/2014-07-09T12:02:32Z]).

I can confirm this bug is still present in 1.3.0, even after upgrading all nodes:

$ curl 0:9200
{
  "status" : 200,
  "name" : "mycluster",
  "version" : {
    "number" : "1.3.0",
    "build_hash" : "1265b1454eee7725a6918f57415c480028700fb4",
    "build_timestamp" : "2014-07-23T13:46:36Z",
    "build_snapshot" : false,
    "lucene_version" : "4.9"
  },
  "tagline" : "You Know, for Search"
}
$ curl 0:9200/_cat/nodes
{"error":"NullPointerException[null]","status":500}

Nothing in the logfile.

@faxm0dem do you have multiple nodes running? if so did you look in the logs for all the nodes?

could you send the output of:

curl 0:9200/_nodes
curl 0:9200/_nodes/stats

thanks

Yes, two nodes, nothing on either side.

Sorry, just now seeing this... @faxm0dem did anything else anomalous happen in the cluster before this? Like, nodes not communicating properly, or running out of mem, anything like that?

Not really. I just upgraded my prod cluster to 1.3.2, and have the same issue.

Getting same error after connecting with logstash. Its working fine as single node and in cluster mode without logstash. Tried with ES 1.3.2 and 1.24 with logstash 1.4.2. is there any workaround for same? But data indexing and query is working fine.

I don't have logstash nodes in my devel cluster, and I still get the error

imotov added a commit to imotov/elasticsearch that referenced this issue Sep 23, 2014

Fix NPE in /_cat/nodes
Query Cache and Suggest stats were introduced in v1.4.0_beta1 and 1.2.0 respectively, therefore they can be null while stats are received from older nodes in the cluster.

Fixes elastic#6297

Just to confirm - was still seeing this in 1.3.4, but upgraded to 1.4.0 today and it is now working correctly.
Thanks!

I upgraded to 1.4.0 today and now I see this error.

"error" : "RemoteTransportException[[Raza][inet[/123.456.17.4:9300]][indices:admin/get]]; nested: ActionNotFoundTransportException[No handler for action [indices:admin/get]]; ",

However I am able to search indices directly

@Grauen are all your nodes 1.4.0?

@Grauen This sounds like a bug that was fixed in #8387. if you are still seeing this problems when all of your nodes are running 1.4.0, then please open a new issue.
