Benjamin Mahler created MESOS-7132:
--------------------------------------
Summary: Fair share can be exceeded due to coarse-grained offer
technique.
Key: MESOS-7132
URL: https://issues.apache.org/jira/browse/MESOS-7132
Project: Mesos
Issue Type: Bug
Components: allocation
Reporter: Benjamin Mahler
Priority: Critical
The current implementation of quota allocation allocates the entire available
resources on an agent when trying to satisfy the quota. What this means is that
quota can be exceeded by the size of an agent.
This is especially problematic for large machines, consider a 48 core, 512 GB
memory server where a role is given 4 cores and 4GB of memory. Given our
current approach, we will send an offer for the entire 48 cores and 512 GB of
memory!
This ticket is to perform fine grained offers when the allocation will exceed
the quota.
