Szilard Nemeth commented on YARN-9318:
--------------------------------------
Sure, I updated the patch with this (almost).
multiplyTo can't call multiplyAndRoundDown directly as multiplyAndRound clones the Resource
but multiplyTo does not.
This is not a problem if the caller retrieves the return value and using it later on, but
can be a problem if the method do get called but the return value is ignored.
Anyway, I did the following:
- modified multiplyAndRoundDown / multiplyAndRoundUp to clone the Resource before passing
it over to multiplyAndRound.
- multiplyAndRound no longer does cloning
- multiplyTo calls multiplyAndRound without cloning first, so it will work as before:
{code:java}
multiplyAndRound(lhs, by, RoundingDirection.DOWN);
{code}
Please check the latest patch!
Thanks!

> org.apache.hadoop.yarn.util.resource.Resources#multiplyAndRoundUp only deals with memory
and vcores while computing the rounded value. It should also consider custom Resource Types
as well.
