[jira] [Updated] (MESOS-4829) Remove `grace_period_seconds` field
from Shutdown event.
[ https://issues.apache.org/jira/browse/MESOS-4829?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Anand Mazumdar updated MESOS-4829:
----------------------------------
Description:
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) in the future. For now, we can just read the value via an environment variable.
