Declining all offers

[Sam Taha <ta...@gmail.com>]

If I want decline ALL offers for say the next 5 minutes, is there an
effective way to do that without completely stopping the framework and
disconnecting from the master?

Write now I am just shutting down the driver and then starting new
driver/scheduler when new jobs are ready.

Thanks,

Looking at the code it doesn't look like the requestResources() feature is
implemented in the master. It is currently a no-op on the master/allocator.
That said the Request protobuf does have an optional slaveId which can be
used to perhaps remove any filters on the slave. Mind filing a ticket?

Thanks Vinod. Yea it would be nice to have the feature to decline offers
from all slaves. I have scenarios in my app where the user can disable
system wide job scheduling/processing or there are cases where jobs are not
scheduled to run for extended periods of time during the day. Disconnecting
and reconnecting to the master are not ideal work around since I may have
long tail jobs running on slaves even though I have no interest in new
offers.

One related question, if I do decline offers from a slave for a set period
of time, the Scheduler.requestResources() call will trigger the Mesos to
start sending me offers as soon as it can and ignore the previous decline
time period, correct?

Hey Sam. You can set a timeout in the "Filters" when you decline an offer.
That will ensure that the framework won't be offered resources for that
slave for the timeout. There is currently no way to decline offers for all
slaves, you have to do it per offer/slave.
