             Summary: Log executor commands w/o verbose logs enabled
                 Key: MESOS-5197
                 URL: https://issues.apache.org/jira/browse/MESOS-5197
             Project: Mesos
          Issue Type: Task
            Reporter: Michael Gummelt


To debug executors, it's often necessary to know the command that ran the executor.  For example, when Spark executors fail, I'd like to know the command used to invoke the executor (Spark uses the command executor in a docker container).  Currently, it's only output if GLOG_v is enabled, but I don't think this should be a "verbose" output.  It's a common debugging need.
