-------------------------------------
Summary: Views: Make view extraction a background task.
Key: AMBARI-7158
URL: https://issues.apache.org/jira/browse/AMBARI-7158
Project: Ambari
Issue Type: Task
Reporter: Tom Beerbower
Assignee: Tom Beerbower
Fix For: 1.7.0
The first time that a view is deployed, the contents of the archive are
extracted to the file system.
Currently view extraction can slow the initial startup of Ambari significantly.
It would be ideal if we could start the view extraction process as background
tasks while Ambari startup is allowed to proceed. This means that an API user
may be able to make requests for view APIs before the view has finished
deploying. We could add a state field to view with the following possible
values ...
PENDING - the view archive has been discovered but the extraction process
has not yet started.
INSTALLING - the view archive is being extracted.
INSTALLED - the view archive is fully extracted and the view is ready to
use.
Until a view is fully installed the API user will not see instances for that
view.
