Zeppelin SSl: Service cannot bind to port 9995

ddharam — Sat, 10 Dec 2016 01:18:16 GMT

I am trying to setup Zeppelin SSl however service cannot start as it cannot bind to port 9995.

There is no fw and iptables is disabled.

Have gone through the ssl setting passowrds are correct and am able to list keystores.

Seeing the following in the error logs:

WARN [2016-12-09 15:01:52,636] ({main} AbstractLifeCycle.java[setFailed]:212) - FAILED org.eclipse.jetty.server.Server@349403b0: java.security.UnrecoverableKeyException: Cannot recover key java.security.UnrecoverableKeyException: Cannot recover key

Hello @ddharam,

This error can have many reasons but a common one is that the password to open SSL keystore is incorrect. Can you please show us the SSL configuration part in Zeppelin? Also please share the keytool command used to list the keystore. Don't forget to hide the vital parts from the output !

Another option is to run Zeppelin in SSL debug mode to get more descriptive log. You can add "-Djavax.net.debug=ssl" in the Zeppelin command line & restart Zeppelin service. Please share the debug log here.

Thanks.

The issue was the password where in different password was set for for keystore and key password. Keeping both same resolved the issue of starting zeppelin service.
