failed to get node info using native transport

[刘凯祥]

Hi Everybody,

I setup a cluster of elaticsearch that it includes three nodes. Elaticsearch version is 2.4.1.

The elaticsearch configuration of one node looks like as:
cluster.name: es_cluster
node.name: es_node1
path.repo: ["/mnt/backups/backup"]
network.host: 192.168.1.104
discovery.zen.ping.unicast.hosts: ["192.168.1.104", "192.168.1.105", "192.168.1.106"]

Now, I want to use the native transport to connect to the ES cluster but I get "failed to get node info" error message after I run below code:
(def conn (es/connect  [["192.168.1.104" 9300] ["192.168.1.105" 9300] ["192.168.1.106" 9300]] {"cluster.name" "es_cluster"}))

The detail error message is:
INFO [2016-11-28 01:11:28,063] elasticsearch[Aldebron][generic][T#2] - org.elasticsearch.client.transport - [Aldebron] failed to get node info for [#transport#-1][localhost.localdomain][inet[/192.168.1.104:9300]], disconnecting...

Who can help me or give some hint for the issue? Thanks you very much.
Also, I don't find firewall issue for the three ES nodes from client and the 9300 port of three nodes are openned.


Thanks

Hi

Is port 9300 open for both TCP and UDP?

thanks a lot..

In my machine:

[root@es_node1 ~]# netstat -tcpln|grep 9300

tcp6       0      0 192.168.1.104:9300      :::*                    LISTEN      2048/java           

tcp6       0      0 192.168.1.104:9300      :::*                    LISTEN      2048/java           

tcp6       0      0 192.168.1.104:9300      :::*                    LISTEN      2048/java           

^C

[root@es_node1 ~]# 

[root@es_node1 ~]# 

[root@es_node1 ~]# netstat -tupln|grep 9300

tcp6       0      0 192.168.1.104:9300      :::*                    LISTEN      2048/java           

[root@es_node1 ~]# 

But , how to open 9300 both tcp and udp?

Hmm, I'm not sure it's needed... I think you should:

* Check the ES logs.

* Check the version of the Java client. Using the same version as the ES servers is safest.

* Try with just one node.

* Ask at https://discuss.elastic.co/.

Not sure if your have solved your problem.   i met similar issue when my client API version was different with the ES cluster version.

[刘凯祥]

Thanks a lot, I solved this problem by change my  ES cluster version to 3.* and it worked.and I tried 1.7* version, it also worked. When using 2.x, this problem occured.

Thank you all the same.
