-------------------------------------

             Summary: Docker pull or run errors result in terrible error 
messages for users
                 Key: MESOS-2260
                 URL: https://issues.apache.org/jira/browse/MESOS-2260
             Project: Mesos
          Issue Type: Bug
            Reporter: Jay Buffington


When the mesos slave gets an error from "docker run" or "docker pull" the error 
message sent back to the user is confusing.  

If the user specifies a bogus image (an image that doesn't exist in the 
registry) the user sees:
    - TASK_LOST: Abnormal executor termination

If dockerd isn't running on the slave for some reason the user sees an 
"Unregistered executor" error.

The user also gets a terrible message if the executor fails to start due to a 
misconfiguration of aurora's -thermos_executor_path or the slave is not 
configured with --containerizer=docker,...

This Jira is likely blocked by MESOS-2200 and MESOS-2020.
