Klaus Ma updated MESOS-3366: ---------------------------- Comment: was deleted (was: Not sure whether we'll support hot update hardwares, for example, increasing memory/disk without shutting down the slave. If so, modules/decorators or child-process are necessary to report hardwares info periodically; and master adjust resources accordingly.) > Allow resources/attributes discovery > ------------------------------------ > > Key: MESOS-3366 > URL: https://issues.apache.org/jira/browse/MESOS-3366 > Project: Mesos > Issue Type: Improvement > Components: slave > Reporter: Felix Abecassis > > In heterogeneous clusters, tasks sometimes have strong constraints on the > type of hardware they need to execute on. The current solution is to use > custom resources and attributes on the agents. Detecting non-standard > resources/attributes requires wrapping the "mesos-slave" binary behind a > script and use custom code to probe the agent. Unfortunately, this approach > doesn't allow composition. The solution would be to provide a hook/module > mechanism to allow users to use custom code performing resources/attributes > discovery. > Please review the detailed document below: > https://docs.google.com/document/d/15OkebDezFxzeyLsyQoU0upB0eoVECAlzEkeg0HQAX9w > Feel free to express comments/concerns by annotating the document or by > replying to this issue. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
