Hi Team,

Please find attached knime logs and screenshot for the same issue.

Hi RG,

this is either a problem with your cluster or with Spark Jobserver configuration. The log files of Spark Jobserver may contain more information:

• /var/log/spark-job-server/spark-job-server.log
• /var/log/spark-job-server/<some-context-name>/spark-job-server.log

 

Best,

Björn
