Sanjay M Pujare commented on APEXCORE-573:
------------------------------------------

Just to be clear the function 
com.datatorrent.stram.plan.physical.PhysicalPlan.getActivationCheckpoint(PTOperator)
 does NOT return what is expected here so we need to be careful about 
terminology here.

The way to do this would be to save the first recoveryCheckpoint in PTOperator 
and return it as the "activation window id" when requested 
(fillPhysicalOperatorInfo).

> Need to return activation window id for physical operators in StramWebServices

> It will be useful to return to the caller the window id the physical operator 
> (re)started from in 
> com.datatorrent.stram.webapp.StramWebServices.getOperatorInfo(int) since this 
> information could be useful in debugging the application.
