Solutions

1. Check the task status string in the trace; only known statuses (e.g. SUCCESS, FAILED, KILLED) are handled.

When it happens

Trigger: ZombieJob encounters a task attempt status it does not recognize when sampling execution times from the job story.

Common situations: See trigger scenarios.
