[jira] [Commented] (MESOS-4547) Introduce TASK_KILLING state.

["Qian Zhang (JIRA)" <ji...@apache.org>]

Qian Zhang commented on MESOS-4547:
-----------------------------------

Do we want to make this a general feature, i.e., always send TASK_KILLING before TASK_KILLED? Or we will send TASK_KILLING only in the case of MESOS-4140?

> Currently there is no state to express that a task is being killed, but is not yet killed (see MESOS-4140). In a similar way to how we have TASK_STARTING to indicate the task is starting but not yet running, a TASK_KILLING state would indicate the task is being killed but is not yet killed.
> This would need to be guarded by a framework capability to protect old frameworks that cannot understand the TASK_KILLING state.
