Jason Lowe commented on YARN-6195:
----------------------------------
Thanks for the patch, [~benson.qiu]!
I'm confused about how labels are supposed to interact with the JMX metrics.
There's only one metric for used capacity in a queue even if there are labels?
If the used proportion of a capacity is updated, it updates the same metric as
for other labels or no label? The metric will always reflect the last update
given at the time the metric is examined, meaning there could be wildly
different results from reading to reading even if things aren't moving that
much on the cluster in reality, e.g.: one reading gets the "fizgig" node
label's usage while another gets the default/no label usage.
MetricsRegistry.java: "mutable long float" and "mutable float integer" should
both be "mutable float"
The tabs flagged by the whitespace check need to be removed.
