Till Rohrmann updated FLINK-22072:
----------------------------------
Description:
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 not 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}
