             Summary: Introduce TASK_GONE task status
                 Key: MESOS-5344
                 URL: https://issues.apache.org/jira/browse/MESOS-5344
             Project: Mesos
          Issue Type: Epic
          Components: master
            Reporter: Neil Conway


The TASK_LOST task status describes two different situations: (a) the task was not launched because of an error (e.g., insufficient available resources), or (b) the master lost contact with a running task (e.g., due to a network partition); the master will kill the task when it can (e.g., when the network partition heals), but in the meantime the task may still be running.

This has two problems:
1. Using the same task status for two fairly different situations is confusing.
2. In the partitioned-but-still-running case, frameworks have no easy way to determine when a task has truly terminated.

To address these problems, we propose introducing a new task status, TASK_GONE, which would be used whenever a task can be guaranteed to not be running.
