Chen He updated YARN-691: ------------------------- Attachment: YARN-691.patch > 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 > 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". -- This message was sent by Atlassian JIRA (v6.1#6144)
