[jira] [Commented] (MESOS-110) Mesos deploys should not restart tasks

    [ https://issues.apache.org/jira/browse/MESOS-110?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13486343#comment-13486343 ] 

Stu Hood commented on MESOS-110:
--------------------------------

This ticket is critical for services that would not normally be preempted except for hardware failures... tasks restarting due to slave restarts adds a shared failure domain to the entire system that is impossible for tasks to avoid, regardless of how well they are replicated.

> Running a long-lived service on Mesos has a significant drawback right now in that Mesos build deploys restart your tasks. This could lead to nontrivial outages for services that have a high warm-up time.  Basically everything would need a graceful restart mechanism that basically allows a shutdown/restart with a new version of the code.
