;jobmanager.task.max.retries.recoverable.error: Defines the maximum number of retries for tasks finished with a RECOVERABLE_ERROR result, either explicity sent by the worker or by the task monitoring of the Task Manager due to the worker not having sent keepAlive signals anymore for a configured period of time. As long as this retry limit is not reached, the Job Manager will recreate the task with a new task ID but the same settings, so that it can be processed by another worker. If the retry count is reached, however, the RECOVERABLE_ERROR will be handled as a FATAL_ERROR. Default: 10.

Configuring the JobManager

The JobManager is configured via the ClusterConfig service. With the "simple" ClusterConfig service, it uses one properties in the "taskmanager" section of clusterconfig.json: 

{
  ...
  "taskmanager": {
    ...
    "maxRetries": 10,
    ...
  },
  ...
}
  • maxRetries: Used to decide how often a task should be retried that has failed with an RECOVERABLE_ERROR, either because the "timeToLive" was exceeded or the worker itself reported such an error. If the retry limit is reached, the task will finally fail with a FATAL_ERROR.
