Tez Vertex Info analysis

[Joe Zhang (SDE)]

Hi Tez experts:

       I am using tez REST API to analysis vertex running information, below is 
what I get . but I am wandering some concepts

<1> what does " numTasks" contains ? what are relationships among numTasks, 
numberCompletedTasks, numKilledTasks , numFailedTasks, numSucceededTasks ?

<2> why does not contains running tasks? How can get the number of running task 
and not started tasks?

<3> whether any task in this vertex failed will called the whole vertex failed??
