IMO, there are two options for batch job:

1. Calculate the accurate min required slot number according to whether the 
ResultPartitionType is PIPELINED or BLOCKING. This is a little complicated.

2. We can just sum up these max-parallelism for different groups. Then both 
streaming and batch job can run successfully. For batch job, user can adjust 
the slot number in configuration. 

 

I would like use the option 2, and the name of getMaximumParallelism will 
change to getSumOfSharingGroupMaximumParallelism

> Currently, it is not possible to run a job with multiple slot sharing groups 
> on the LocalExecutor. The problem is that we determine the number of required 
> slots simply by looking for the max parallelism of the job but do not 
> consider slot sharing groups.
