Tim Thorpe commented on AMBARI-15388:
-------------------------------------
Patch file is mostly changes to the java classes. The upgrade*.xml files have
been updated to have distinct naming for the service check sections:
SERVICE_CHECK1, SERVICE_CHECK2 and SERVICE_CHECK3 for rolling upgrade.
> Custom services need a way to integrate in the upgrade process

> Currently the upgrade is defined as a series of xml files specific to the
> current stack version and the target stack version. Each upgrade xml defines
> the overall sequence of the upgrade and what needs to be done for each
> service. Custom services need to be able to specify their upgrade process
> and how those steps fit into the upgrade process.
