------------------------------------------
Assignee: Alexander Rukletsov
> Scheduler hang when registration fails (due to bad role)
> --------------------------------------------------------
>
> Key: MESOS-7872
> URL: https://issues.apache.org/jira/browse/MESOS-7872
> Project: Mesos
> Issue Type: Bug
> Components: scheduler driver
> Affects Versions: 1.4.0
> Reporter: Till Toenshoff
> Assignee: Alexander Rukletsov
> Labels: framework, reliability, scheduler
>
> I'm finding that if framework registration fails, the mesos driver client
> will hang indefinitely with the following output:
> {noformat}
> I0809 20:04:22.479391 73 sched.cpp:1187] Got error ''FrameworkInfo.role'
> is not a valid role: Role '/test/role/slashes' cannot start with a slash'
> I0809 20:04:22.479658 73 sched.cpp:2055] Asked to abort the driver
> I0809 20:04:22.479843 73 sched.cpp:1233] Aborting framework
> {noformat}
> I'd have expected one or both of the following:
> - SchedulerDriver.run() should have exited with a failed Proto.Status of some
> form
> - Scheduler.error() should have been invoked when the "Got error" occurred
> Steps to reproduce:
> - Launch a scheduler instance, have it register with a known-bad framework
> info. In this case a role containing slashes was used
> - Observe that the scheduler continues in a TASK_RUNNING state despite the
> failed registration. From all appearances it looks like the Scheduler
> implementation isn't invoked at all
> I'd guess that because this failure happens before framework registration,
> there's some error handling that isn't fully initialized at this point.
