>             Project: Kafka
>          Issue Type: Bug
>          Components: streams
>    Affects Versions: 0.10.2.1
>            Reporter: Xavier Léauté

>
> If streams shutdown is initiated during state restore (e.g. an uncaught exception is
thrown) streams will not shut down until all stores are first finished restoring.
> As restore progresses, stream threads appear to be taken out of service as part of the
shutdown sequence, causing rebalancing of tasks. This compounds the problem by slowing down
the restore process even further, since the remaining threads now have to also restore the
reassigned tasks before they can shut down.
