> 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.
