-------------------------------------
Summary: Refreshing Ambari Dashboard or HDFS Dashboard shows
console error Cannot read property 'hosts' of undefined
Key: AMBARI-23414
URL: https://issues.apache.org/jira/browse/AMBARI-23414
Project: Ambari
Issue Type: Bug
Components: ambari-server, ambari-web
Affects Versions: trunk, 2.7.0
Reporter: JaySenSharma
Assignee: JaySenSharma
In a NameNode HA enabled cluster, When we refresh the Ambari UI page then on
next time refresh we see the following error on the Browser console :
{code}
Uncaught TypeError: Cannot read property 'hosts' of undefined
at app.js:213145
at Array.filter (<anonymous>)
at app.js:213144
at Array.map (<anonymous>)
at Class.setMultipleGroupLinks (app.js:213143)
at Class.setQuickLinksSuccessCallback (app.js:212862)
at Class.opt.success (app.js:180150)
at fire (vendor.js:1141)
at Object.fireWith [as resolveWith] (vendor.js:1252)
at done (vendor.js:8178)
{code}
This happens because the expression "this.get('shouldSetGroupedLinks')" returns
"false" first time but next time it returns "true" but the possibility is that
the expression "this.get('masterGroups.length')". is still returns "false".
(means the "masterGroups" array is still having no or one element).
