-----------------------------------
Summary: Stop masters and agents from downgrading resources to
pre-reservation-refinement format.
Key: MESOS-8372
URL: https://issues.apache.org/jira/browse/MESOS-8372
Project: Mesos
Issue Type: Task
Components: agent, master
Reporter: Michael Park
Due to the 1.x compatibility story, we need to downgrade the resources on
masters and agents for the rest of 1.x. One option for 2.0 would be for 1.x to
be upgradable to 2.0 (i.e., 2.0 would read pre-/post- reservation refinement
formats), but for 2.0 to not be downgradable to 1.x, but rather, downgradable
to 1.4.x (i.e., 2.0 can checkpoint in post- format only.)
If we restrict the upgrade path to 1.x -> 2.0 -> 2.y, we can also, starting
from 2.1 to only read
post- format, as well.
