Alexander Rukletsov updated MESOS-4302: --------------------------------------- Issue Type: Improvement (was: Bug) > Offer filter timeouts are ignored if the allocator is slow or backlogged. > ------------------------------------------------------------------------- > > Key: MESOS-4302 > URL: https://issues.apache.org/jira/browse/MESOS-4302 > Project: Mesos > Issue Type: Improvement > Components: allocation > Reporter: Benjamin Mahler > Assignee: Alexander Rukletsov > Priority: Critical > Labels: mesosphere > > Currently, when the allocator recovers resources from an offer, it creates a > filter timeout based on time at which the call is processed. > This means that if it takes longer than the filter duration for the allocator > to perform an allocation for the relevant agent, then the filter is never > applied. > This leads to pathological behavior: if the framework sets a filter duration > that is smaller than the wall clock time it takes for us to perform the next > allocation, then the filters will have no effect. This can mean that low > share frameworks may continue receiving offers that they have no intent to > use, without other frameworks ever receiving these offers. > The workaround for this is for frameworks to set high filter durations, and > possibly reviving offers when they need more resources, however, we should > fix this issue in the allocator. (i.e. derive the timeout deadlines and > expiry based on allocation times). > This seems to warrant cherry-picking into bug fix releases. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
