Chun-Hung Hsiao created MESOS-9785:
--------------------------------------
Summary: Frameworks recovered from reregistered agents are not
reported to master `/api/v1` subscribers.
Key: MESOS-9785
URL: https://issues.apache.org/jira/browse/MESOS-9785
Project: Mesos
Issue Type: Bug
Components: HTTP API
Reporter: Chun-Hung Hsiao
Currently when an operator subscribes to the {{/api/v1}} master endpoint, it
would receive a {{SUBSCRIBED}} event carrying information about all known
frameworks, including registered ones and unregistered ones. If an unregistered
framework reregisters later, a {{FRAMEWORK_UPDATED}} event would be sent to the
operator.
However, if an operator subscribes to the {{/api/v1}} master endpoint after a
master failover but before any of the frameworks and agents reregisters,
{{SUBSCRIBED}} would contain no recovered framework information. When a agent
with running tasks reregisters later, unregistered frameworks of those tasks
will be recovered, but no {{FRAMEWORK_ADDED}} will be sent to the operator, so
the operator will receive {{TASK_ADDED}} for those tasks with unknown framework
IDs.
