-------------------------------------
Summary: Remove `grace_period_seconds` field from Shutdown event.
Key: MESOS-4829
URL: https://issues.apache.org/jira/browse/MESOS-4829
Project: Mesos
Issue Type: Task
Reporter: Anand Mazumdar
There are two ways in which a shutdown of executor can be triggered:
1. If it receives an explicit `Shutdown` message from the agent.
2. If the recovery timeout period has elapsed, and the executor still hasn’t
been able to (re-)connect with the agent.
Currently, the executor library relies on the field `grace_period_seconds`
having a default value of 5 seconds to handle the second scenario.
https://github.com/apache/mesos/blob/master/src/executor/executor.cpp#L608
The driver used to trigger the grace period via a constant defined in
src/slave/constants.cpp.
https://github.com/apache/mesos/blob/master/src/exec/exec.cpp#L92
The agent may want to force a shorter shutdown grace period (e.g.
oversubscription eviction may have shorter deadline).
