Summary: UI optimization: control configurations loading
Key: AMBARI-3494
URL: https://issues.apache.org/jira/browse/AMBARI-3494
Project: Ambari
Issue Type: Task
Components: client
Affects Versions: 1.4.2
Reporter: Andrii Tkach
Assignee: Andrii Tkach
Fix For: 1.4.2
Attachments: AMBARI-3494.patch
In different places configs are loaded for some types(core-site, mapred-site,
etc.), The idea is to store them into localdb. On first load we check if there
is configs for this type if no then request server and put them into localdb,
otherwise check the whether tags version have changed, if so then request
server as well, in rest cases we load configs from local storage. Also preserve
advanced configs, since they immutable we need to load them only one time. To
implement this: create configController in global controllers dir and operate
storing, requesting, verifying configs via that controller.
