--------------------------------------
Okay, then no doc needed. Thanks [~ekoifman].
> Running Hive Jobs with Tez cause templeton to never report percent complete
> ---------------------------------------------------------------------------

> Key: HIVE-9351
> URL: https://issues.apache.org/jira/browse/HIVE-9351
> Project: Hive
> Issue Type: Bug
> Components: WebHCat
> Affects Versions: 0.14.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
> Fix For: 0.15.0
>
> Attachments: HIVE-9351.patch
>
>
> Currently, when submitting Hive jobs through WebHCat and Hive is configured
> to use Tez, the "percentComplete" field returned by WebHCat is empty.
> LaunchMapper in WebHCat parses stderr of the process that it launches to
> extract map = 100%, reduce = 100% for Map/Reduce case. With Tez the content
> of stderr looks like
> {noformat}
> Map 1: -/- Reducer 2: 0/1
> Map 1: -/- Reducer 2: 0(+1)/1
> Map 1: -/- Reducer 2: 1/1
> {noformat}
> WebHCat should handle that as well.
> WebHCat will follow HIVE-8495 and report (completed tasks)/(total tasks) as a
> percentage.
