-----------------------------------------
Summary: Filter NaN values from JMX json interface
Key: HADOOP-18954
URL: https://issues.apache.org/jira/browse/HADOOP-18954
Project: Hadoop Common
Issue Type: Improvement
Components: common
Reporter: Bence Kosztolnik
As we can see in this [Yarn
documentation|https://hadoop.apache.org/docs/stable/hadoop-yarn/hadoop-yarn-site/ResourceManagerRest.html]
beans can represent Float values as NaN. These values will be represented in
the response JSON like:
{noformat}
...
"GuaranteedCapacity": NaN,
...
{noformat}
Based on the [JSON doc|https://www.json.org/] NaN is not a valid JSON token (
however some of the parser libs can handle it ), so not every consumer can
parse values like this.
To be able to parse NaN values, a new feature flag should be created.
The new feature will replace the NaN values with null values.
