Why Are Logs Not Written to the OBS Bucket After a DLI Flink Job Fails to Be Submitted for Running?

Mode for storing generated job logs when a DLI Flink job fails to be submitted or executed. The options are as follows:

  • If the submission fails, a submission log is generated only in the submit-client directory.
  • You can view the logs generated within 1 minute when the job fails to be executed on the management console.

    Choose Job Management > Flink Jobs, click the target job name to go to the job details page, and click Run Log to view real-time logs.

  • If the running fails and exceeds 1 minute (the log dump period is 1 minute), run logs are generated in the application_xx directory.
Flink dependencies have been built in the DLI server and security hardening has been performed based on the open-source community version. To avoid dependency package compatibility issues or log output and dump issues, be careful to exclude the following files when packaging:
  • Built-in dependencies (or set the package dependency scope to "provided")
  • Log configuration files (example, log4j.properties/logback.xml)
  • JAR file for log output implementation (example, log4j).

On this basis, the taskmanager.log file rolls as the log file size and time change.
