Hi @Raj Swarnim It means that java is unable to find that class in the classpath. Can you share the steps through which you got to this error?

@Raj Swarnim I think the config file is causing the issue. Can you try to delete the classifier configuration from the detector.yml file

@Suvodeep Pyne dealing with the same issue at the moment. What exactly do you recommend deleting from the detector.yml file?

@Leon Graveland I think the

classifier

config has been removed. Can you try deleting that line?

@Suvodeep Pyne Thanks a lot for the swift response. In the detector.yml file, I cannot find any

classifier

config. https://github.com/project-thirdeye/thirdeye/blob/master/thirdeye-dashboard/config/detector.yml

Let me ellaborate a bit on the steps I took. /.run-frontend.sh and ./run-backend.sh are both not working for me. ./run-frontend.sh (adding -Xdiag to the command)

Copy code

root@d7c0a0aaf524:/thirdeye/thirdeye-dashboard# java -Xdiag -Dlog4j.configurationFile=log4j2.xml -cp "./target/thirdeye-dashboard-1.0.0-SNAPSHOT.jar" org.apache.pinot.thirdeye.dashboard.ThirdEyeDashboardApplication "./config"

I did follow this blog without any success: https://medium.com/@gregsimons_84/apache-pinot-thirdeye-quickstart-helper-b5d8a95a22eb by adding plugins to the pom.xml and ran install.sh again.
