    -The streaming mode changes the startup behavior of Flink: The system is not 
    -bringing up the managed memory services with preallocated memory at the beginning.
    -Flink streaming is not using the managed memory employed by the batch operators.
    -By not starting these services with preallocated memory, streaming jobs can benefit
    -from more heap space being available.
    -
    -Note that you can still start batch jobs in the streaming mode. The memory manager
    -will then allocate memory segments from the Java heap as needed.

     ### Optional: Adding JobManager/TaskManager instances to a cluster
     
     You can add both TaskManager or JobManager instances to your running cluster with the
`bin/taskmanager.sh` and `bin/jobmanager.sh` scripts.
     
     #### Adding a TaskManager
     <pre>
    -bin/taskmanager.sh (start [batch|streaming])|stop|stop-all)
    +bin/taskmanager.sh start|stop|stop-all
     </pre>
     
     #### Adding a JobManager
     <pre>
    -bin/jobmanager.sh (start cluster [batch|streaming])|stop|stop-all)
    +bin/jobmanager.sh start|stop|stop-all

    Could you preserve the "cluster" or "local" parameter?

>
> Currently, TaskManagers are still started in the batch mode.
> I have the impression that more users are actually using Flink for stream processing,
and, the streaming mode also allows batch workloads.
> It would be nice to change that for the 1.0 release
