> Invalid NaN values in Hadoop REST API JSON response
> ---------------------------------------------------
>
> Key: YARN-691
> URL: https://issues.apache.org/jira/browse/YARN-691
> Project: Hadoop YARN
> Issue Type: Bug
> Components: resourcemanager
> Affects Versions: 0.23.6, 2.0.4-alpha
> Reporter: Kendall Thrapp
> Assignee: Chen He
> Fix For: 2.3.0
>
> Attachments: YARN-691.patch

> I've been occasionally coming across instances where Hadoop's Cluster
> Applications REST API
> (http://hadoop.apache.org/docs/r0.23.6/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html#Cluster_Applications_API)
> has returned JSON that PHP's json_decode function failed to parse. I've
> tracked the syntax error down to the presence of the unquoted word NaN
> appearing as a value in the JSON. For example:
> "progress":NaN,
> NaN is not part of the JSON spec, so its presence renders the whole JSON
> string invalid. Hadoop needs to return something other than NaN in this case
> -- perhaps an empty string or the quoted string "NaN".
