> Remove Refresh Query Hint From Upgrade DAO

> Key: AMBARI-20847

> Project: Ambari
> Issue Type: Task
> Components: ambari-server
> Affects Versions: 2.4.0
> Reporter: Jonathan Hurley
> Assignee: Jonathan Hurley
> Priority: Critical
> Fix For: 2.5.1

> Attachments: AMBARI-20847.patch

>
> Repeated requests to the {{org.apache.ambari.server.orm.dao.UpgradeDAO}}
> methods during upgrades can cause large delays retrieving active upgrades.
> This is because the {{QueryHint.REFRESH}} is being used in almost every
> method. This causes a re-read on every {{UpgradeEntity -> UpgradeGroupEntity
> -> UpgradeItemEntity}} in the entire database for every query.
> These query hints should be removed.
