[jira] [Commented] (AMBARI-23827) Update extension link doesn't
persist to the Ambari DB
[ https://issues.apache.org/jira/browse/AMBARI-23827?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16471943#comment-16471943 ]
Tim Thorpe commented on AMBARI-23827:
-------------------------------------
Please note, you *do not* need to install the stack or the service(s) in the extension version.
You need to have 2 different versions of the same extension and follow the steps listed in the description above.

> ------------------------------------------------------
>
> Key: AMBARI-23827
> URL: https://issues.apache.org/jira/browse/AMBARI-23827
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.6.0, 2.7.0
> Reporter: Tim Thorpe
> Priority: Major
>
> Update extension link doesn't persist to the Ambari DB. The REST API will return the proper results but the DB won't be altered. This results in the extension link reverting to the previous extension after an Ambari server restart.
> Here are the reproduction steps:
> * Install ambari-server
> * Install 2 versions of an extension - just the extension definitions with their service definitions
> * Restart ambari-server
> * Link the 1st version of the extension
> * Update the extension link to the 2nd version of the extension
> * Verify the Ambari DB
> * Restart ambari-server
> * Verify the list of links via the REST API (post restart)
> *
> ## Link the 1st version*
> [root@node1 ~]# curl -u admin:admin -H 'X-Requested-By: ambari' *-X POST* -d '{"ExtensionLink": {"stack_name": "HDP", "stack_version": "2.5", "extension_name": "IBM-Big_SQL", *"extension_version": "5.0.2.0"*}}' [http://node1.fyre.ibm.com:8080/api/v1/links/]

> ## Verify the extension link created*

> ## Update the link to the 2nd extension version*
> [root@node1 ~]# curl -u admin:admin -H 'X-Requested-By: ambari' *-X PUT* -d '{"ExtensionLink": {"stack_name": "HDP", "stack_version": "2.5", "extension_name": "IBM-Big_SQL", *"extension_version": "5.0.3.0"*}}' [http://node1.fyre.ibm.com:8080/api/v1/links/1]
