> Let RpcEndpoint.start/shutDown throw exceptions
> -----------------------------------------------

> Key: FLINK-4847
> URL: https://issues.apache.org/jira/browse/FLINK-4847
> Project: Flink
> Issue Type: Sub-task
> Components: Distributed Coordination

> Assignee: Till Rohrmann
>
> The {{RpcEndpoint.start}} and {{RpcEndpoint.shutDown}} methods should be
> allowed to throw exceptions if things go wrong. Otherwise, exceptions will be
> given to a callback which handles them later, even though we know that we can
> fail the components right away (as it is the case for the {{TaskExectuor}},
> for example).
