[jira] [Created] (IGNITE-12614) Disallow silent deactivation of cluster to prevent in-mem data loss.

Vladimir Steshin created IGNITE-12614:
-----------------------------------------

             Summary: Disallow silent deactivation of cluster to prevent in-mem data loss.
                 Key: IGNITE-12614
                 URL: https://issues.apache.org/jira/browse/IGNITE-12614
             Project: Ignite
          Issue Type: Bug
            Reporter: Vladimir Steshin


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 deactivate 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.
