Eric Payne commented on YARN-10343:
-----------------------------------
Thanks again [~Jim_Brennan] and [~jhung] for your reviews.
I have attached patch 001 for trunk.
- This patch renamed the MB variables to indicate they are bytes, not megabytes.
- I left the code as it is wrt subtracting reserved resources from used
resources:
{code:title=MetricsOverviewTable#render}
+ usedMemoryBytes -= reservedMemoryBytes;
+ usedVCores -= reservedVCores;
{code}
-- I didn't want to make changes to the various allocateResource paths that
call {{ResourceUsage#incUsed}}.
- I was able to use the root queue's {{ParentQueue#getNumContainers}} to get
all labeled and non-labeled containers. However, it also includes reserved
containers. In this case, it may be fine since there is not a separate
"Reserved Containers" field.
> Legacy RM UI should include labeled metrics for allocated, total, and
> reserved resources.
