Wilfred Spiegelenburg commented on YARN-9344:
---------------------------------------------
HI [~uranus] yes this is a problem nice catch.
However don't we have a more generic problem with the fact that we offer the
node to this application attempt at all? The reservation is one thing but I
think we should shortcut this assignment completely. If the specific request
does not fit at all we need to move to the next request for the application
attempt.
That would mean we need to move it one call up into the
{{assignContainer(FSSchedulerNode node, boolean reserved)}} instead of where it
is now.
Does that make sense to you?
