failure*
- *Added test that validates that TaskInfo is transferred only once
across recoveries*
- *Manually verified the change by running a 4 node cluser with 2
JobManagers and 4 TaskManagers, a stateful streaming program, and killing one
JobManager and two TaskManagers during the execution, verifying that recovery
happens correctly.*
