Oleg Nechiporenko created AMBARI-7400:
-----------------------------------------
Summary: Slider View: Most view parameters should be made required
Key: AMBARI-7400
URL: https://issues.apache.org/jira/browse/AMBARI-7400
Project: Ambari
Issue Type: Bug
Components: contrib
Affects Versions: 1.7.0
Reporter: Oleg Nechiporenko
Assignee: Oleg Nechiporenko
Priority: Critical
Fix For: 1.7.0
First, we should rename view parameters to below. Also we should mark them
required as mentioned below.
* {{hdfs.url}}. Required = true
* {{yarn.rm.url}}. Required = true
* {{yarn.rm.scheduler.url}}. Required = true
* {{zookeeper.quorum}}. Required = true
* {{ganglia.host}}. Required = *false*
* {{ganglia.addtional.clusters}}. Required = *false*
* {{slider.user}}. Required = *false* (see BUG-23250)
The code on client to automatically load from Ambari should be cleaned away.
On app load, the view should validate the parameters and display error messages
in an error section. If there are errors (invalid values, empty strings, etc.),
the App should be put in error mode where it does not load further.
There should be an App wide location to easily determine parameters and their
values (Maybe a _App.ViewParameter.sliderUser_ etc.).
In the Create App wizard, _Enable Metrics_ action should only be enabled only
when {{ganglia.addtional.clusters}} and {{ganglia.host}} are provided.
