> Key: AMBARI-13753
> URL: https://issues.apache.org/jira/browse/AMBARI-13753
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 1.5.0
> Reporter: Siddharth Wagle
> Assignee: Siddharth Wagle
> Fix For: 2.1.3
>
>
> Problems:
> - Deleted hostcomponent rows re-appear
> - Inconsistencies in hostcomponentstate and hostcomponentdesiredstate tables
> Analysis:
> - Stale entity references cached that point to dettached entites and may get
> persisted in altogether different transaction
> - Cascaded persist annotation mixed with manual bi-directional persist
> operations. The manual persist was done since there are cached references in
> the object hierarchy at different levels. The Casade addition seems to have
> been an after thought added on even though manual bi-directional perist
> laways existed.
> Patch details:
> - Make sure cached references are refreshed on getter / setter methods
> - Remove Cascaded persist for only those relations that could result in
> un-intentional persist of the relationship with downstream objects. eg:
> ServiceComponentHostDesiredStateEntity
> - Marked HostRoleCommand and ExecutionCommand as non-Cacheable entites for JPA
> - Make sure bi-directional persist is present on non-Cascaded entities
> - Removed refresh() calls that were responsible for refreshing cached entity
> objects
