> Key: FLINK-11851

> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination
> Affects Versions: 1.7.2, 1.8.0
> Reporter: Till Rohrmann
> Assignee: Till Rohrmann
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.7.3, 1.8.0

>
> The {{ClusterEntrypoint}} provides the executor of the common {{RpcService}}
> to the {{HighAvailabilityServices}} which uses the executor to run io
> operations. In I/O heavy cases, this can block all {{RpcService}} threads and
> make the {{RpcEndpoints}} running in the respective {{RpcService}}
> unresponsive.
> I suggest to introduce a dedicated I/O executor which is used for io heavy
> operations.
