------------------------------------------
Summary: Introduce "global" decision policy for unhealthy tasks.
Key: MESOS-6171
URL: https://issues.apache.org/jira/browse/MESOS-6171
Project: Mesos
Issue Type: Improvement
Affects Versions: 1.0.0
Reporter: Alexander Rukletsov
Currently, if the task is deemed unhealthy, i.e. it failed a health check a
certain number of times, it is killed by both default executors:
[command|https://github.com/apache/mesos/blob/b053572bc424478cafcd60d1bce078f5132c4590/src/launcher/executor.cpp#L299]
and
[docker|https://github.com/apache/mesos/blob/b053572bc424478cafcd60d1bce078f5132c4590/src/docker/executor.cpp#L315].
This is what can be called "local" kill policy.
While local kill policy can save some network traffic and unload the scheduler,
there are cases, when a scheduler may want to decide what—and when—to do. This
is what can be called "global" policy, i.e. the health check library reports
whether a health check failed or succeeded, while the executor forwards this
update to the scheduler without taking any action.
