Andrew Mashenkov commented on IGNITE-9053:
------------------------------------------
Why you think this will not help?
AaddNotification method creates a future and put it into a map.
CQ processor has a discovery listener that releases on futures that are alredy
in map.
I believe that the only fix you need is justo check if node is gone after
future has been put to map but before waiting on it.
Exchange and discovery threads hanging on unlocking should be resolved with
IGNITE-9290.
