> Hive Rolling Upgrade Is No Longer Supported In Ambari

> HS2 RU expects all users to be using zookeeper based JDBC URLs. However, few
> users are using these new Zookeeper discovery urls and they use the old
> format, directly specifying the hostname and port number for the HS2 instance
> it connects to. During RU, the HS2 port number changes and users using old
> url have an outage. Hive needs to be able to support RU without changing the
> port.
> Due to too many Hive Client user outages as a result of the RU workflow for
> HIve, the decision is to just change RU to bounce the HS2 process, knowing
> that there will be down time and causing all active queries to fail. So the
> runbook for the HS2 process will look like:
> * We will no longer change the Hive port at all during either RU or EU.
> * During an RU, we will present a message if Hive is present that indicates
> that Hive is not rolling and it will be taken down.
> * Run the Hive deregister command to remove the ZK entries for the Hive
> Servers
> * Hive will be shutdown, without draining, during an RU and a new instance
> started up on the same port.
> In addition, we need to remove the warnings that were added as part of
> AMBARI-17319.
