Till Rohrmann commented on FLINK-8712:
--------------------------------------
Yes, the user should definitely be enabled to configure the number of slots in
a local {{MiniCluster}}. It could also be possible to take the slot sharing
groups into account when calculating the number of slots with which the
{{MiniCluster}} is started.
> Cannot execute job with multiple slot sharing groups on LocalExecutor

> Key: FLINK-8712
> URL: https://issues.apache.org/jira/browse/FLINK-8712
> Project: Flink
> Issue Type: Bug
> Components: Local Runtime
> Affects Versions: 1.5.0
> Reporter: Till Rohrmann
> Priority: Critical
>
> 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.
>
> {code:java}
> // set up the streaming execution environment
> final StreamExecutionEnvironment env =
> StreamExecutionEnvironment.getExecutionEnvironment();
> env.setParallelism(1);
> final DataStreamSource<Integer> input = env.addSource(new InfinitySource());
> final SingleOutputStreamOperator<Integer> different = input.map(new
> MapFunction<Integer, Integer>() {
> @Override
> public Integer map(Integer integer) throws Exception {
> return integer;
> }
> }).slotSharingGroup("Different");
> different.print();
> // execute program
> env.execute("Flink Streaming Java API Skeleton");{code}
