Dmitry Lysnichenko updated AMBARI-7237:
---------------------------------------
Description:
On stack 1.3 stop service, then put it into MM. Try to open Service Actions
menu - start option is inactive.
Here is how service state calculation worked: if component is in MM, we don't
take it's state into account when calculating entire service state. At the
extreme case when all components of a service are in MM, we return DISABLED
state for the service.
To fix the current jira, I've implemented a special handling for the case when
all service components (or entire service) are in MM as follows:
# we iterate over all master & slave componens and determine the best
component state (e.g. INSTALLED -> STARTED)
# now the best state for MM component becomes a calculated state for an
entire service
That means that if all components of service are in MM and at least one
component is started, entire service will be showed as started.
