Eric Badger commented on YARN-10707:
------------------------------------
Thanks for the updated patch, [~zhuqi]! It's much cleaner and much smaller now

float nodeGpuUtilization = 0F;
+ float nodeGpus = 0F;
try {
if (gpuNodeResourceUpdateHandler != null) {
nodeGpuUtilization =
gpuNodeResourceUpdateHandler.getNodeGpuUtilization();
+ nodeGpus =
+ gpuNodeResourceUpdateHandler.getNodePhysGpus();
}
} catch (Exception e) {
LOG.error("Get Node GPU Utilization error: " + e);
}
{noformat}
Ideally this wouldn't be GPU-specific and we could add all plugin utilizations
to the nodeUtilization object. But that is beyond the scope of this JIRA, so I
think this is fine. However, I think we can get a better name than
{{nodeGpus}}. Maybe {{TotalNodeGpuUtilization}}?
Additionally, why are we sending the average GPU utilization to the NM metrics,
but the total GPU utilization to the RM? Memory and CPU are consistent across
the two. I don't understand why GPU is different.
