Jonathan Eagles commented on YARN-9563:
---------------------------------------
I'm +1 on patch 003. I'll wait for Hadoop QA results as well as give some time
for other reviewers before committing this. I'm guessing this patch is targeted
for all lines back to 2.8?
> Resource report REST API could return NaN or Inf

> The Resource Manager's Cluster Applications and Cluster Application REST APIs
> are sometimes returning invalid JSON. This was addressed in YARN-6082.
> However, the fix only fixes the calculation in one site and does not
> guarantee to avoid the problem.Likewise, generating NaN/Inf can break the web
> GUI if the columns cannot render non-numeric values.
> The suggested fix is to check for NaN/Inf in the protob. The protob replaces
> NaN/Inf by 0.0f.
