> 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.
