Installation troubleshooting

Local Apache Spark does not start

  • check if the metabase connection string is set properly, especially when SQL Server named instance is used
  • check Querona and Spark logs under %PROGRAMDATA%\Querona\logs for clues

Installation was successful, but I’m unable to connect to Administrative Portal

If you configured Querona to use SSL, it is possible that you used a badly configured SSL certificate (designated in installer as UNVERIFIED.) To fix the issue, you need to uninstall Querona and install it again without SSL or use a verified certificate.
