Ranger KMS - Installation issue on Non-Kerberized HDP 2.4 cluster

Hi. i'm trying to install Ranger KMS on HDP 2.4 (Non-Kerberized cluster), and running into issues.

The error i get is shown below (not able to connect to SQL Server using 'root' user)

Any ideas on this ?

@Karan Alang

Looks like root user does not have access from remote host. Please update root user to allow remote access

@Karan AlangI mean to say that , at Mysql side change the user access permissions to connect from remote host. You can follow http://benrobb.com/2007/01/15/howto-remote-root-access-to-mysql/ to do that.

@apappu - thanks, i was able to make this work.

Another question - per my understanding, i'll be able to install & use Ranger KMS in a non-Kerberized environment also.

Can you pls. confirm.

Thanks!
