[jira] [Commented] (AMBARI-16030) Ambari version history: Add ambari_version_history table for record keeping history of ambari versions

["Alejandro Fernandez (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/AMBARI-16030?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15253109#comment-15253109 ] 

Alejandro Fernandez commented on AMBARI-16030:
----------------------------------------------

I suggest renaming stop_time to end_time.

What will happen if the user attempts to upgrade from version x to y but it fails (perhaps it did a partial upgrade of some sort).
Then they discard that particular upgrade, and pick some other version such as z. In this case, we would want to know that upgrade x->y failed.

If the user does end up deleting ambari-server.log, it would be useful to collect some error statements in this table, as well as the status.

> When investigating customer issues, information about history about Ambari versions is missing. We rely on this information to be provided in the EAR. Many times information in the EAR is inaccurate. Also information about when the Ambari upgrades actually happened in the past is completely missing. 
> Instead of relying on this information to be provided, Ambari should record Ambari upgrade history in Ambari DB.
