Konstantinos Karanasos commented on YARN-7670:
----------------------------------------------
Also, one more thing:
bq. I have mentioned in the javadoc for the attemptAllocationOnNode method that
the numContainers will be ignored and the Scheduler will only try to allocate a
single container on the requested node.
I know, but isn't it better to throw at least a warning, so that people know
they are using it wrong? Or you assume it is okay to have multiple containers
in the request and we place only one?
