---------------------------------
Summary: Update FrameworkInfo.principal on framework
re-registration
Key: MESOS-2842
URL: https://issues.apache.org/jira/browse/MESOS-2842
Project: Mesos
Issue Type: Bug
Reporter: Vinod Kone
Assignee: Aditi Dixit
>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.
