Yan Xu created MESOS-8602:
-----------------------------
Summary: Subscribers::send incorrectly assumes frameworks are
registered
Key: MESOS-8602
URL: https://issues.apache.org/jira/browse/MESOS-8602
Project: Mesos
Issue Type: Bug
Reporter: Yan Xu
We observed this in prod
{noformat}
F0214 00:36:15.746939 3827787 master.cpp:11190] Check failed: 'framework' Must
be non NULL
{noformat}
which is here in code:
[https://github.com/apache/mesos/blob/9635d4a2d12fc77935c3d5d166469258634c6b7e/src/master/master.cpp#L11203]
h2. Diagnosis
The checks were added in in
[https://github.com/apache/mesos/commit/cf331184714f692f21988a53fd04fa64fbbb3aba]
MESOS-8469,
{code:java}
Framework* framework =
master->getFramework(event.task_added().task().framework_id());
CHECK_NOTNULL(framework);
{code}
However as least when we recover tasks when the agent reregisters after a
master failover, the frameworks may not have reregistered yet so they don't
show up in the result from {{master->getFramework}}. Such checks failed to
consider this.
