Yan Xu commented on MESOS-1456:
-------------------------------
A one-off fix for ShedulerProcess: https://reviews.apache.org/r/22250/
> Metric lifetime should be tied to process runstate, not lifetime.

> Key: MESOS-1456
> URL: https://issues.apache.org/jira/browse/MESOS-1456
> Project: Mesos
> Issue Type: Bug
> Components: statistics
> Affects Versions: 0.19.0
> Reporter: Dominic Hamon
> Assignee: Dominic Hamon
>
> The usual pattern for termination of processes is {{terminate(..); wait(..);
> delete ..;}} but the {{SchedulerProcess}} is terminated and then deleted some
> time later.
> If the metrics endpoint is accessed within that period, it never returns as
> it tries to access a {{Gauge}} that has a reference to a valid PID that is
> not getting any timeslices (the {{SchedulerProcess}}). A one-off fix can be
> made to the {{SchedulerProcess}} to move the metrics add/remove calls to
> {{initialize}} and {{finalize}}, but this should be the general pattern for
> every process with metrics.
