Design

When user submit the job, set the following property in the jobEnv of jobConfig. If the job's user command fails, the container will be kept for 1 weeks. And user could debug the container after ssh to it. After debugging, user should manually stop it to recycle the system resources.

When submitting job from webportal:

when submitting job from json file:

  "jobEnvs": {
    "isDebug": true
  }

When you job failed, click into the Go to Tracking Page and looking into the stdout. You could find following log.

[INFO] USER COMMAND START

job has finished with exit code 2
=============================================================================
======   The job container failed, so it will be reserved for 1 week   ======
======          After debugging, please stop the job manually.         ======
