Dominic Hamon created MESOS-1456: ------------------------------------ Summary: 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
