> Provide More Warnings and Messages About Hive's Port Change During Upgrade
> --------------------------------------------------------------------------

> Key: AMBARI-17319
> URL: https://issues.apache.org/jira/browse/AMBARI-17319
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.4.0
> Reporter: Jonathan Hurley
> Assignee: Jonathan Hurley
> Priority: Critical
> Fix For: 2.4.0

> Attachments: AMBARI-17319.patch

>
> After upgrading from HDP 2.2.4.2 to HDP 2.3.2, the
> {{hive.server2.thrift.port}} changed from 10000 to 10010.
> For users and applications which reference Hive via a direct URL/port
> combination instead of a discovery URL, they will no longer be able to
> contact Hive.
> Due to the timing of the next Ambari release, there is a risk of regression
> with any attempt to fix this issue. The best option is to provide a more
> wizard-like approach where Ambari can use the upgrade packs to ask questions
> pertaining to the upgrade. The results of those questions will be passed
> along with the upgrade pack when starting an upgrade so that rudimentary
> decision paths can be taken while performing orchestration. *However, this is
> out of scope for this release*.
> Instead, the following tasks can be chosen to be implemented in part or as a
> whole in an attempt to alleviate this issue.
> *Recommended*
> h5. Task 1 (Simple Messages)
> h6. Development effort: 1 day
> - A new pre-requisite check will be created which will determine if the
> upgrade is rolling and if Hive is installed. If both conditions are met, a
> {{WARNING}} will be triggered which will say something similar to:
> bq. You have chosen to perform a rolling upgrade and Hive is currently
> installed. Hive supports rolling upgrades, but its port will change as a
> result of the upgrade. If this is not the desired behavior, then the port can
> be changed back to its original value after the upgrade has completed.
> - A new message will be added and displayed to the user post-finalization.
> bq. The hive server port has changed as a result of this rolling upgrade. If
> this port change is not desired, then you can now use Ambari to return hive
> to its original port.
> h5. Task 2 (Messages To Alter Configurations)
> h6. Development effort: 4 days total
> - A new pre-requisite check will be created which will determine if the
> upgrade is rolling and if Hive is installed. If both conditions are met, a
> {{WARNING}} will be triggered which will say something similar to:
> bq. You have chosen to perform a rolling upgrade and Hive is currently
> installed. Hive supports rolling upgrades, but its port will change as a
> result of the upgrade. If this is not the desired behavior, then you can
> choose to set the {{ambari.upgrade.hive.rolling}} property to {{false}} in
> {{hive-site}} before continuing with this upgrade. When set to {{false}},
> Hive's port will not change during the upgrade, but Hive will incur downtime
> while it is restarted during the upgrade.
> - The Hive upgrade scripts will change to look for
> {{ambari.upgrade.hive.rolling}} and will choose to do a {{stop}} and a
> {{start}} instead of a {{deregister}}
> - The XML upgrade packs will be changed to look for
> {{ambari.upgrade.hive.rolling}} and only change the hive port based on this
> property being {{true}}.
