Hi I'm runing spark notebooks on Fabric trial since last month and it's been working great.
But just from today afternoon, notebooks do not start the spark session, returning this type of error:
Livy session has failed. Error code: SparkCoreError/UnexpectedSessionState. SessionInfo.State from SparkCore is Error: Encountered an unexpected session state Error while waiting for session to become Idle. Error description:"Cluster creation failed due to an unexpected system error from a runtime related dependency.
Can any expert help ASAP?
Thanks,
