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!
