Subject [jira] [Updated] (YARN-9563) Resource report REST API could return NaN or Inf
Date Fri, 17 May 2019 17:37:00 GMT

     [ https://issues.apache.org/jira/browse/YARN-9563?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ahmed Hussein updated YARN-9563:
--------------------------------
    Description: 
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.
