I keep getting below error both on 5.3.2 and 5.4.0 when using Java Transport Client.  
occasionally i get valid response, trying 3 node cluster in a single machine.

NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{PCD5ssO9QrKeqLea1XFsaw}{127.0.0.1}{127.0.0.1:9300}]]

This probably relates to your other thread.

I tried all the ports, 9300,9301,9302, still the same, very intermittent.

Found the Issue, the issue is with version of the Transport Client library, i was using 5.0.0 Transport java driver for 5.4.0 ES , however when i changed it to 5.3.2 as mentioned here [Option "client.transport.sniff" not working with v5.4.0 Transport Client](https://discuss.elastic.co/t/option-client-transport-sniff-not-working-with-v5-4-0-transport-client/85899)

Everything works fine , don't see the issue anymore.

Thanks  
Sam
