    For the off-heap memory case, the JVM heap memory should be reduced regardless of eager
or lazy memory allocation. I think this can be changed to
    
    ```bash
    if useOffHeapMemory; then
    ```

> 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
