Hello,  
I have spun up a free tier Ubuntu EC2 instance and installed Dremio community version “dremio-community-15.5.0-202105040508160960-dddd4dca.tar.gz”.

However, when I start the services, I get an error something like this -

02:07:29,121 |-INFO in ch.qos.logback.classic.joran.JoranConfigurator@4b2c5e02 - Registering current configuration as safe fallback point

Dremio is exiting. Failure while starting services.

I’m unable to isolate the root cause. Any pointers will be helpful.

Thanks,

@harsha_g2 Try 2 things

- Try to restart again
- If that does not work

- Go to “/var/lib/dremio/data”
- mv db db\_broken
- Start Dremio again
