Description

On 900 node cluster we did an express upgrade from HDP-2.3 to HDP-2.4. After install packages was done, the action to do express upgrade was clicked and the POST call to trigger EU took more than 3 minutes. Due to this, UI timed out and showed an error message saying EU failed - however, in the backend it continued and correctly started the upgrade.

Services installed were:
