Subject: Re: the dependence length of RDD, can its size be greater
Yes. Imagine an RDD that results from a union of other RDDs.

Hi all,
The RDD code keeps a member as below:
dependencies_ : seq[Dependency[_]]
It is a seq, that means it can keep more than one dependency.

Is it possible that its size is greater than one please?
If yes, how to produce it please? Would you like show me some
