--------------------------------
Summary: Provide custom reason for cascaded kill in a task group
Key: MESOS-8768
URL: https://issues.apache.org/jira/browse/MESOS-8768
Project: Mesos
Issue Type: Improvement
Reporter: Zhitao Li
Currently, if a task fails in a task group, other active tasks in the same
group will see _TASK_KILLED_ without any custom reason. We would like to
provide a custom reason like _*REASON_TASK_GROUP_KILLED*_ to distinguish
whether the task is killed upon request of scheduler or upon a cascaded failure.
Open question: does any framework depends the value of this reason? If not, we
probably can just change the reason without a opt-in mechanism from framework
(i.e, a new framework capability).
