Need to change 9300 port to connect

Elastic Stack Elasticsearch
1

Hi,

I want to deploy ES on a server which already has another application using
9300 port. When I start ES, it automatically select next free port like
9302 which is expected.

Problem is that I am unable to connect to ES cluster even if I specify 9302
port in transport client, log shows that client is still trying to connect
to 9300 port.

Client client = new TransportClient()
.addTransportAddress(new InetSocketTransportAddress("host1", 9302))

  • [Jacob "Jake" Fury] failed to get local cluster state for
    [#transport#-1][nds3070558][inet[10.52.192.144:9300]], disconnecting...

org.elasticsearch.transport.ReceiveTimeoutTransportException:
[][inet[10.52.192.144:9300]][cluster/state] request_id [0] timed out after
[5044ms]

Can someone please confirm if it is possible to run ES if 9300 port is not
available and if so provide me pointer on how to correctly specify port
when creating java client.

Thanks,
Ashish

I disabled multicast and enabled unicast with right host and port mapping
and that helped me to connect.

Let me know if there is any other better alternative.

Thanks,

Have you updated the elasticsearch.yml configuration file on all of the
hosts on which you run ES, and then uncommented the following setting and
changed its value to 9302?

Set a custom port for the node to node communication (9300 by default):

transport.tcp.port: 9300

So, change it to:

transport.tcp.port: 9302

Hope this helps.
