Perhaps the best way is to read the code.
The Decision tree is implemented by 1-tree Random forest, whose entry point
is `run` method:
https://github.com/apache/spark/blob/master/mllib/src/main/scala/org/apache/spark/ml/tree/impl/RandomForest.scala#L88
I'm not familiar with the so-called algorithm
It would be good to know which paper has inspired to implement the version
which we use in spark 2.0 decision trees ?

It's a good question. People have been publishing papers on decision trees
and various methods of constructing and pruning them for over 30 years. I
think it's rather a question for a historian at this point.

Read this explanation but wondering if this algorithm has the base from a
research paper for detail understanding.

Is there a reference to the research paper which is implemented in spark
2.0 ?

Which algorithm is used under the covers while doing decision trees FOR
SPARK ?
for example: scikit-learn (python) uses an optimised version of the CART
algorithm.
