> Rethink UnfulfillableSlotRequestException class hierarchy

> Key: FLINK-22072
> URL: https://issues.apache.org/jira/browse/FLINK-22072
> Project: Flink

>
> The ResourceManager currently can throw 2 different exceptions if not enough
> slots are available:
> UnfulfillableSlotRequestException, if a slot could not be acquired, and no TM
> in the cluster could even theoretically provide it (due to the resource
> profiles not matching)
> NoResourceAvailableException, if a slot could be acquired, because none are
> free or a task executor, that could theoretically provide it, could not be
> allocated
> Despite being fairly similar in terms of semantics, hierarchy wise these are
> completely separate.
> {code}
> UnfulfillableSlotRequestException < ResourceManagerException < FlinkException
> NoResourceAvailableException < JobException
> {code}
