> 1. Execute a streaming job which will increase memory usage beyond configured memory
limits during mapping phase. TaskMemoryManager should logs a map task's process-tree's status
just before killing the task. 
> 2. Execute a streaming job which will increase memory usage beyond configured memory
limits during reduce phase. 	TaskMemoryManager should logs a reduce task's process-tree's
