Re: forcing framework to re-schedule?

[haosdent]

If you want to kill the task from the scheduler, you just need to call
`killTask`(
https://github.com/apache/mesos/blob/1.0.x/include/mesos/scheduler.hpp#L257
).
If you want to kill the task by health check, you could try to set the
correct `consecutive_failures` number (
https://github.com/apache/mesos/blob/1.0.x/include/mesos/v1/mesos.proto#L358
).

 Hi, @victor What's your health check agent used for? Because Mesos
 supports health checks now.

 What would be the mechanism to "communicate" failure to the framework
 to cause specific outcome? For example: how can i use failure to cause
 framework to reschedule deployment on different node?

It checks if process is functional. I don't think standard healthchecks
wouldn't be sufficient for my purpose and my question still stands: how  to
use result...

If the target you perform health check is your task, Mesos support health
check by a command. When your task reaches the health task failure limit,
the task would be killed and then your framework could launch the task
again when receives the `TASK_KILLED` in `statusUpdate`.

Hi, @victor What's your health check agent used for? Because Mesos supports
health checks now.
