             Summary: Stop-and-Start Upgrade: Apply configs from multiple major stack versions.
                 Key: AMBARI-13100
                 URL: https://issues.apache.org/jira/browse/AMBARI-13100
             Project: Ambari
          Issue Type: Story
            Reporter: Dmitry Lysnichenko
            Assignee: Dmitry Lysnichenko


When performing a Stop-and-Start Upgrade from HDP 2.1 -> 2.3, we need to apply configs
for multiple stack versions (2.2 and 2.3).
The same should apply once 2.2 -> 2.4 is available.

This is meant to handle the following cases,
HDP 2.2 config changes:
stack already defines property a
add property b
drop property c
rename c to d

HDP 2.3 config changes:
add property e
drop property a
rename d to e

So the overall effect is,

drop property a
add b, and e
rename c to e
