Pruning decision tree in Spark

Hi there,

Say, I have a deeper tree that needs to be pruned to create an optimal
tree. For example, in R it can be done using *rpart/prune *function.

Is it possible to prune a* Spark MLlib/ML-based decision tree* while
performing a classification or regression task?




Regards,
