Greg Mann created MESOS-9681:
--------------------------------
Summary: Update framework principal on re-registration
Key: MESOS-9681
URL: https://issues.apache.org/jira/browse/MESOS-9681
Project: Mesos
Issue Type: Improvement
Components: master
Reporter: Greg Mann
>From the design doc:
This is a bit involved because ‘principal’ is used for authentication and rate
limiting.
The authentication part is straightforward because a framework with updated
‘principal’ should authenticate with the new ‘principal’ before being allowed
to re-register. The ‘authenticated’ map already gets updated when the framework
disconnects and reconnects, so it is fine.
For rate limiting, Master:failoverFramework() needs to be changed to update the
principal in ‘frameworks.principals’ map and also remove the metrics for the
old principal if there are no other frameworks with this principal (similar to
what we do in Master::removeFramework()).
The Master::visit() and Master::_visit() should work with the current semantics.
NOTE that the principal type used in Mesos has changed since this ticket was
originally filed; the master code should be checked thoroughly to ensure that
the above is still relevant!
