Thanks.

How to calculate the similarity of the movies in Spark MLlib, like mahout's org.apache.mahout.cf.taste.hadoop.similarity.item.ItemSimilityJob?

There is no equivalent; Spark MLlib has just the bare bones of model building algorithms. You would write it yourself. It would not be too much Spark code to write though. Although calculating all-pairs is always potentially too huge to contemplate.
