Vladimir Steshin updated IGNITE-12614:

Description:
Currently, anyone is able to deactivate cluster with command line utility
(control.sh). Probably with JMX too. That would lead to data loss when the
persistence is off. In-memory data is erased during deactivation. Such behavior
can be considered as unexpected to user.
Suggestions:
1) Disallow silent deactivation of cluster keeping caches. Show a warning
like “Your cluster has in-memory cache configured. During deactivation all data
from these caches will be cleared!”
2) Add param ‘--force’ which skips the warning message.
