@StephanEwen , yes, I already noticed that today and this test can pass in
my local machine. And I executed it for many loops and found that it may fail
sometimes because of the sort sequence of generated job vertex may change for
`IterationHead` and `Source`. I will make it stable and notice you when pass
CI.
Thank you!
> Aggregate ResourceSpec for chained operators when generating job graph

> This is a part of fine-grained resource configuration in flip-6.
> In *JobGraph* generation, each *JobVertex* may contain a series of chained
> operators, and the resource of *JobVertex* should be aggregation of
> individual resource in chained operators.
> For memory resource in *JobVertex*, the aggregation is the sum formula for
> chained operators, and for cpu cores resource, the aggregation is the maximum
> formula for chained operators.
