-----------------------------------
Summary: 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
Reporter: Kendall Thrapp
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".
