Spark library has a library for ML labelled as MLib. This Apache Spark library has algorithms for the functions of classification, regression, clustering, collaborative filtering, dimensionality reduction, etc. The classification includes classifying things into different categories. For example, in emails the classification is done in categories of inbox, sent, drafts, spam and so on. Clustering example is bifurcating the news on the basis of the title and content of the news.
