Subject [jira] [Commented] (YARN-5242) Update DominantResourceCalculator to consider all resource types in calculations

-------------------------------

HI [~vvasudev]
Thanks for the patch. A quick doubt.
{{fitsIn}} is generally used as a public API in many critical places inside scheduler. In
this patch, {{IllegalArgumentException}} is thrown and it may fail heartbeats etc. As I see,
we were handling 2 return cases from *fitsIn* (success / failure).  Could we report failure
instead of exception. Or do you see this as a recurring failure which needs to handled as
fail-fast?

> The fitsIn function in the DominantResourceCalculator only looks at memory and cpu. It
should be modified to use all available resource types.
