Troubleshooting

Problem 1

  • Symptom

    The Spark job fails to be executed, and the job log indicates that the Java server connection or container fails to be started.

  • Solution

    Check whether the host information of the datasource connection has been modified. If not, modify the host information by referring to Configuring MRS Host Information in DLI Datasource Connection. Then create and submit a Spark job again.

    A Spark job fails to be executed and "KrbException: Message stream modified (41)" is displayed in the job log.

  • Solution

    Delete all renew_lifetime = xxx configurations from the krb5.conf configuration file. Then create and submit a Spark job again.
