Vinod Kone commented on MESOS-7966:
-----------------------------------
We need more master logs around this crash to be able to debug this. Especially
the logs around when the maintenance endpoints are hit until you see the crash.
Can you please attach those logs to the ticket? We will be able to find the
root cause easily with that information.
> check for maintenance on agent causes fatal error
> -------------------------------------------------
>
> Key: MESOS-7966
> URL: https://issues.apache.org/jira/browse/MESOS-7966
> Project: Mesos
> Issue Type: Bug
> Components: master
> Affects Versions: 1.1.0
> Reporter: Rob Johnson
> Assignee: Armand Grillet
> Priority: Blocker
> Labels: reliability
>
> We interact with the maintenance API frequently to orchestrate gracefully
> draining agents of tasks without impacting service availability.
> Occasionally we seem to trigger a fatal error in Mesos when interacting with
> the api. This happens relatively frequently, and impacts us when downstream
> frameworks (marathon) react badly to leader elections.
> Here is the log line that we see when the master dies:
> {code}
> F0911 12:18:49.543401 123748 hierarchical.cpp:872] Check failed:
> slaves[slaveId].maintenance.isSome()
> {code}
> It's quite possibly we're using the maintenance API in the wrong way. We're
> happy to provide any other logs you need - please let me know what would be
> useful for debugging.
> Thanks.
