-----------------------------------
Summary: DAGClient waitForCompletion output is confusing
Key: TEZ-1476
URL: https://issues.apache.org/jira/browse/TEZ-1476
Project: Apache Tez
Issue Type: Bug
Reporter: Siddharth Seth
Priority: Critical
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.
