FatalError when starting Dremio 2.0 RC on MacOs

Hi, i’ve installed Dremio RC 2.0 Community on Mac Os

It seems the upgrading process is failing, as I get the following error in server.out file.
As a consequence Dremio does not start.
I can be useful to know that the previous installed version was Dremio 1.2.2 Community Edition

I’ve got the same issue with an installation from 1.4.4 to 2.0.0rc on a windows desktop

I’m also getting the same error with an installation on Mac High Sierra going from 1.4 to 2.0.0rc.

Thanks for reporting. If people could share the log files (server.log/server.out), this would be useful.

Thanks for the logs. We identified the issue and are working on fix.
