-------------------------------------
Summary: Include reason in TASK_KILLED updates
Key: MESOS-6786
URL: https://issues.apache.org/jira/browse/MESOS-6786
Project: Mesos
Issue Type: Improvement
Reporter: Gastón Kleiman
At least the following reasons can lead to a task being killed:
* The executor decided to kill it, e.g., if it was unhealthy.
* The framework requested the kill.
* An operator requested the kill.
The executors bundled with Mesos don't set a reason in the {{TaskStatus}}
message, making it hard to debug task kills.
I think that we should extend the {{TaskStatus.Reason}} enum with reasons for
those three cases.
In the case of health check failures, the executors should also populate the
{{message}} field with useful debugging information.
