> 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.
