Rationale for this change
When partition count of execution plan is 0, the job will hang because available tasks of running stage will be empty, then
get_running_stage_id
method ofExecutionGraph
will return None.datafusion-ballista/ballista/scheduler/src/state/execution_graph.rs
Line 969 in e7cb3d5
So the running stage will keep running and won't be converted to successful/failed stage.
