-------------------------------------------
Summary: Slider View: View UI should load data from Ambari API
Key: AMBARI-7231
URL: https://issues.apache.org/jira/browse/AMBARI-7231
Project: Ambari
Issue Type: Task
Components: ambari-client
Affects Versions: 1.7.0
Reporter: Antonenko Alexander
Assignee: Antonenko Alexander
Priority: Critical
Fix For: 1.7.0
Slider View UI currently calls
{{/api/v1/views/SLIDER/versions/1.0.0/instances/SLIDER_1/resources/status}} API
to determine if view is enabled, and if not, why it is not enabled.
UI when loaded, should not use this GET call anymore. Rather it should
determine this information by directly calling Ambari REST api, and then PUT
this and other information to
{{/api/v1/views/SLIDER/versions/1.0.0/instances/SLIDER_1}}.
UI should determine whether to enable view, and reasons why if not.
The view could be disabled for multiple reasons. One or all of the below could
be reasons why the view is disabled
* HDFS, YARN, ZK not installed
* HDFS, YARN, ZK not started
If any of the above are true, the reason(s) should be shown in appropriate
message(s) (as we do currently).
Additionally, the following information should also be loaded from Ambari on
load
* Cluster name
* HDFS location ({{fs.defaultFS}} config from {{core-site}})
* YARN RM location ({{yarn.resourcemanager.address}} from {{yarn-site}})
* YARN RM Scheduler location ({{yarn.resourcemanager.scheduler.address}} from
{{yarn-site}})
* ZK Quorum path - comma separated path of all {{ZK_SERVER_HOST:clientPort}}
values. {{clientPort}} is from {{zookeeper-env}}. Example:
{{c6401:2181,c6402:2181,c6403:2181}}.
All the above information (cluster name, HDFS location, YARN RM location, YARN
RM Scheduler location, ZK Quorum path) should then be PUT to {{properties}} key
of {{/api/v1/views/SLIDER/versions/1.0.0/instances/SLIDER_1}}, from where GET
can be called later during app running.

This effort is crucial for Slider view to work in a standalone environment.
