Benjamin Bannier created MESOS-8966:
---------------------------------------
Summary: Operations can contain explicit zero resources
Key: MESOS-8966
URL: https://issues.apache.org/jira/browse/MESOS-8966
Project: Mesos
Issue Type: Bug
Components: master
Reporter: Benjamin Bannier
The master does not make sure that resources given as part of operations are
not empty. While we fixed the case of frameworks sending non-empty resources
which would internally be rounded to zero as part of MESOS-8945, we still do
not validate that e.g., frameworks do not attempt to {{RESERVE}} {{cpus:0}} or
an empty port range.
We still want to allow specifying some resources as explicitly zero to
distinguish absent or empty resources (currently e.g., used to trigger
autodetection of {{gpus}} or in the future to set zero quota guarantees), so it
seems that we could update the validation in {{validateAndUpgradeResources}} to
require non-empty resources where needed.
