Description

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.
