   The most big factor is file formats instead of Spark side.
   For example, in the above example, ORC files are small because it supports a 
special encoding when the input data is sorted with a fixed increment. For 
Parquet files, the result will be different.

   Oh, this is interesting. I know removing `Sort` before `Repartition` will 
result in different data distribution because `Repartition` uses 
`RoundRobinPartitioning`. Because I think repartition doesn't guarantee 
shuffled data distribution, so I thought it is okay.
   
   Now seems different data distribution causes difference storage output size. 
I think it is because to repartition sorted data using `RoundRobinPartitioning` 
can generate more compact output.

   Hi, @gatorsmile . Technically, this only handles `host/port` parsing inside 
`core` module. I'm sure that this is a meaningful step inside Spark. However, 
we didn't test anything on IPv6. Like what we did for JDK11, I expect lots of 
hurdle both inside and outside Spark.

   @viirya Sorry, can you explain? I don't see how it changes the technique, it 
just allows models from multiple folds to be run in parallel. `MLUtils.kFold` 
is doing k-fold cross validation, not repeated random sub-sampling validation, 
right?

   Seems like the implementation of `processIterator` is pretty similar to

just allows models from multiple folds to be run in parallel.

Review comment:
   Yeah, this fixes the weird compile error (Arrays + generic types are 
stricter in Scala 2.13) though I don't directly see what it has to do with type 
M. Still, this is an API change I think MiMa will fail and I think I need 
another workaround for _that_. This is an obscure method that isn't even called 
by tests, AFAICT, so not sure it even has coverage.
