Unable to start elastic search 2.4 after enabling shield


When I am starting the elasticsearch after enabling shield SSL, the elastic search fails to start.

License will expire on [Friday, July 13, 2018]. If you have a new license, please update it.

Otherwise, please reach out to your support contact.

Commercial plugins operate with reduced functionality on license expiration:

- shield

- Cluster health, cluster stats and indices stats operations are blocked

- All data operations (read and write) continue to work

The error, "[ERROR][shield.transport.netty ] [Namor McKenzie] SSL/TLS handshake failed, closing channel: null" is very generic. I am not able to isolate the issue with this error.

Any help is appreciated.


2.4 has reached EOL, is there any reason you are still using it?

Hi Warkolm,

Thank you for the quick response.

This is an issue observed for one of my clients. Elastic search is integrated with Talend platform. The latest versions of Talend has the supported version of Elastic Search. However, in this use case, my client is using a older version of Talend.

We should use Elastic Search for some more time. Can you please provide some inputs to debug this issue ?
