------------------------------
Summary: Ambari server should not crash with NPE when parsing HTTP
response for YARN RM properties
Key: AMBARI-18588
URL: https://issues.apache.org/jira/browse/AMBARI-18588
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: trunk
Reporter: Di Li
Assignee: Di Li
Fix For: trunk
When YARN RM HTTP response is a 404, the response body is empty and this
results in an empty responseMap, that later caused Ambari server to crash with
NPE when it tries to read properties from the responseMap.
This JIRA proposes to set property values as null when the responseMap is null
(due to empty body passed back from the YARN web server side).
