> During an upgrade, there is no ability to arbitrarily pause the request and
> gain control of the cluster back. If there is a pre-defined manual task or a
> failure which cannot be skipped, then the user has the ability to pause the
> upgrade (which in turn aborts the request temporarily).
> There should be a way to do this during the upgrade while it's running a
> command. The following are some example of ways in which this would be useful:
> - During a long running rolling upgrade, the customer may need to regain
> control of Ambari to restart a component. They cannot necessarily wait for
> the upgrade to finish or wait for a spot where the UI presents them the
> option to pause.
> - If an upgrade is having difficulty due to a configuration property in
> {{ambari.properties}}, the administrator will want to pause the upgrade in
> order to shut down Ambari and make the configuration changes.
