New Contributor

I am using "Metron 0.4.1 with HDP 2.5 bare-metal install on CentOS 7 with MariaDB for Metron REST", once done all the configuration part, I have started the Ambari service. In Ambari UI,

1. Zeppelin Notebook: I am unable to start this services.

2. Metron REST: I am able to start "Metron REST". but after 10 seconds, it was automatically stopping.

Any suggestions for the above 2 issues.

Below is the screenshot of my UI.

Can you post the contents of the REST log at /var/log/metron/metron-rest.log? That should have more information about why REST is not starting.
