Execute failed: Yarn application has already ended! It might have been killed or unable to launch application master.

Hi Team,

I am gettig below error when I try to execute Spark Context Node - 

ERROR Create Spark Context 3:9        Execute failed: Yarn application has already ended! It might have been killed or unable to launch application master. (for details see View > Open KNIME log)
WARN  Spark Joiner         3:104      Spark context of first input incompatible with Spark context of second input

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

 

Thanks,

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
