> 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.
