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.
@Alluri Krishna Raju, Could you please post the failure logs from the ambari background operations window or log files for the start failures?
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.
Hi, I'm facing the same issue with Metron REST service. The error message showing in metron-rest.log is as follows:

Please share your thoughts on the same.
