Chun-Hung Hsiao created MESOS-9616:
--------------------------------------
Summary: `Filters.refuse_seconds` declines resources not in offers.
Key: MESOS-9616
URL: https://issues.apache.org/jira/browse/MESOS-9616
Project: Mesos
Issue Type: Bug
Components: allocation
Reporter: Chun-Hung Hsiao
The
[documentation|http://mesos.apache.org/documentation/latest/scheduler-http-api/#accept]
of {{Filters.refuse_seconds}} says:
{quote}
Also, any of the offer’s resources not used in the ACCEPT call (e.g., to launch
a task or task group) are considered declined and might be reoffered to other
frameworks, meaning that they will not be reoffered to the scheduler for the
amount of time defined by the filter.
{quote}
Consider an {{ACCEPT}} call with just a {{CREATE}} operation, but no {{LAUNCH}}
or {{LAUNCH_GROUP}}. The {{CREATE}} call will generate a persistent volume
resource that is *not* in the offer's resources, but it will still not be
reoffered to the scheduler for the amount of time defined by the filter.
Also, the term *used* is vague here. If we have an {{ACCEPT}} call with a
{{CREATE}} on a disk followed by a {{DESTROY}} on the created persistent
volume, would the disk be considered *used*?
