> Replace NMClient with NMClientAsync in YarnResourceManager
> ----------------------------------------------------------
>
> Key: FLINK-9410
> URL: https://issues.apache.org/jira/browse/FLINK-9410
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Coordination
> Affects Versions: 1.5.0, 1.6.0, 1.7.0
> Reporter: Till Rohrmann
> Assignee: zhangminglei
> Priority: Critical
>
> Currently, the {{YarnResourceManager}} uses the synchronous {{NMClient}}
> which is called from within the main thread of the {{ResourceManager}}. Since
> these operations are blocking, we should replace the client with the
> {{NMClientAsync}} and make the calls non blocking.
