Jeff Zhang commented on TEZ-1476:
---------------------------------

Meet the same issue. And I remember the behavior is different from tez-0.4 where status will be logged every some period even no task is completed.

> When a DAG is submitted - "2014-08-21 16:38:06,153 INFO  [main] rpc.DAGClientRPCImpl (DAGClientRPCImpl.java:log(428)) - Waiting for DAG to start running" is logged.
> After this, nothing seems to get logged till the first task completes.
> It would be useful to log when the state changes to RUNNING - as well as at least one line stating the number of tasks, etc (0% progress line). Also, progress could be logged every few seconds irrespective of whether it has changed or not to give the impression that the job has not just gotten stuck.
