----------------------------------
Summary: Master doesn't handle scheduler driver downgrade from
HTTP based to PID based
Key: MESOS-7867
URL: https://issues.apache.org/jira/browse/MESOS-7867
Project: Mesos
Issue Type: Bug
Components: master
Affects Versions: 1.3.0
Reporter: Ilya Pronin
Assignee: Ilya Pronin
When a framework upgrades from a PID based driver to an HTTP based driver,
master removes its per-framework-principal metrics ({{messages_received}} and
{{messages_processed}}) in {{Master::failoverFramework}}. When the same
framework downgrades back to a PID based driver, the master doesn't reinstate
those metrics. This causes a crash when the master receives a message from the
failed over framework and increments {{messages_received}} counter in
{{Master::visit(const MessageEvent&)}}.
