Hi Maxime, The slave decomissioning feature is in-progress. For updates, see https://issues.apache.org/jira/browse/MESOS-1474 and its sub-JIRAs MESOS-1475 and MESOS-1476 This includes "Provide a way for frameworks to be notified when resources are requested to be relinquished. This gives the framework to proactively move a task before it is forcibly killed. It also allows the automation of operations like: "please drain these slaves within 1 hour.""
Hope that helps! -Adam- On Mon, Jun 30, 2014 at 1:44 PM, Maxime Brugidou <[email protected]> wrote: > hi, > > Is there any task status update that a scheduler can hook to when a slave > will be decommissioned?
