Lefty Leverenz commented on HIVE-7236:
--------------------------------------

Right, the only place I see is the design doc:

* [Hive on Tez | https://cwiki.apache.org/confluence/display/Hive/Hive+on+Tez]

Ideally we'd create a user doc, but as a quick fix how about adding an update note to the Job Monitoring or Job Diagnostics section?

* [Job Monitoring | https://cwiki.apache.org/confluence/display/Hive/Hive+on+Tez#HiveonTez-Jobmonitoring]
* [Job Diagnostics | https://cwiki.apache.org/confluence/display/Hive/Hive+on+Tez#HiveonTez-Jobdiagnostics]

However if an Updates & Improvements section would be useful for other new information, it should go at the end of the design doc and this could go there with a link from Job Monitoring or Diagnostics.

Also, the user docs could have a stub pointing to the design doc.

> Currently, the only logging in TezJobMonitor is for completed tasks. 
> This makes it hard to locate task stalls and task failures. Failure scenarios are harder to debug, in particular when analyzing query runs on a cluster with bad nodes.
> Change the job monitor to log running & failed tasks as follows.
> {code}
> Map 1: 0(+157,-1)/1755     Reducer 2: 0/1  
> Map 1: 0(+168,-1)/1755     Reducer 2: 0/1  
> Map 1: 0(+189,-1)/1755     Reducer 2: 0/1  
> Map 1: 0(+189,-1)/1755     Reducer 2: 0/1 
> {code}
> That is 189 tasks running, 1 failure and 0 complete.
