In that case containers should be > preserved so the automatic restart can recover them. > # The NM is not running under supervision and a rolling upgrade is not being > performed. In that case the shutdown should kill all containers since it is > unlikely the NM will be restarted in a timely manner to recover them. > # The NM is not running under supervision and a rolling upgrade is being > performed. In that case the shutdown should not kill all containers since a > restart is imminent due to the rolling upgrade and the containers will be > recovered. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
