@StephanEwen , I have submitted the modifications as we confirmed before.
It needs to change some previous codes and excuse my late update because of a
little busy last week.
BTW, I found another potential bug in
`StreamingJobGraphGeneratorTest.testChainStartEndSetting`. If this test is not
executed at first, it would cause NPE problem because the `idCounter` in
`StreamTransformation` is static. And I want to fix it in another separate jira
although I have modified it in order to confirm the `clean verify` successful.
> 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.
