[jira] [Created] (AURORA-1326) Mesos task states do not have one-to-one mapping to scheduler task states

Maxim Khutornenko created AURORA-1326:
-----------------------------------------

             Summary: Mesos task states do not have one-to-one mapping to scheduler task states
                 Key: AURORA-1326
                 URL: https://issues.apache.org/jira/browse/AURORA-1326
             Project: Aurora
          Issue Type: Task
          Components: Scheduler
            Reporter: Maxim Khutornenko


Mesos tasks states don't map directly to scheduler task states. This will create problems if/when mesos task reconciliation evolves to handle partial task diffs and starts respecting TaskState values sent from the scheduler. Specifically, these active states need to be handled deterministically to avoid Mesos state mismatch and a possible task kill:
