Tez counters are null

[Grandl Robert]

Hi guys,

I am running Tez 0.5 compiled from master. In VertexImpl.java, when a 
TASK_STATUS_UPDATE_EVENT happens, I am trying to print the whole counters for 
the task. 


The way I did it in tez-0.4 was simply: 

TaskStatusUpdateEvent sEvent = (TaskStatusUpdateEvent) tezEvent.getEvent();
LOG.info(sEvent.getCounters().toString());

However, whenever a TASK_STATUS_UPDATE_EVENT happens, in Tez-0.5 compiled from 
master, it shows that sEvent.getCounters() is null. 


Do I miss something ?
