> Restarting Some Components During a Suspended Upgrade Fails Due To Missing
> Upgrade Parameters
> ---------------------------------------------------------------------------------------------
>
> Key: AMBARI-19617
> URL: https://issues.apache.org/jira/browse/AMBARI-19617
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.5.0
> Reporter: Jonathan Hurley
> Assignee: Jonathan Hurley
> Priority: Critical
> Fix For: 2.5.0
>
> Attachments: AMBARI-19617.patch
>
>
> While attempting to restart a component that has complicated upgrade logic,
> the upgrade parameters are not sent to the agents. This can cause some
> components to fails during a suspended upgrade restart.
> Example:
> - Begin express upgrade from {{2.3.6.0-3796}} to {{2.5.3.0-37}}
> - {{HIVE_METASTORE}} couldn't start b/c of a missing Kerberos property:
> {code}
> resource_management.core.exceptions.Fail: Configuration parameter
> 'hive.server2.authentication.kerberos.principal' was not found in
> configurations dictionary!
> {code}
> - Chose to {{Ignore and Proceed}} which means that none of the Metastore SQL
> files ran.
> - Paused the upgrade (presumably at Finalize) and try to start Metastore. It
> fails to start because the new HDP 2.5 bits are using a non-upgraded
> database. That causes the {{-info}} option to fail and makes Ambari think it
> needs to run {{-initSchema}}.
> RCA: Metastore failed to start during upgrade and the admin chose to skip it.
> This caused schema upgrade logic not to run. Ambari can examine the
> {{upgrade_suspended}} property to determine if we need to run upgrade
> commands while restarting Metastore during an upgrade.
> However, it might be more prudent to simply send along the suspended upgrade
> properties so that any actions which might need to happen (such as invoking
> an upgrade script during the restart) can happen when the upgrade is
> suspended.
