Summary: The Web Client Upgrade Wizard Does Not Wait Long Enough
When Creating a Large Upgrade
Key: AMBARI-20759
URL: https://issues.apache.org/jira/browse/AMBARI-20759
Project: Ambari
Issue Type: Bug
Components: ambari-web
Affects Versions: 2.4.2
Reporter: Antonenko Alexander
Assignee: Antonenko Alexander
Fix For: 2.5.1
When creating an upgrade on a large cluster, the backend currently takes a very
long time to create the data and persist it. Although steps are being taken to
greatly reduce this time, it could still take up to several minutes for this
request to go through.
The web client currently doesn't wait long enough for the upgrade to being. It
will produce an error message saying that the upgrade could not be created and
then gets confused when the upgrade eventually shows up. It also allows a user
to try to create another upgrade while the first is still being generated.
STR:
- Create a rolling upgrade on a cluster with 1000 hosts where every host has 15
components installed.
