      Description

      There are still some algorithms based on mllib, such as KMeans. For now, many mllib common class (such as: Vector, DenseVector, SparseVector, Matrix, DenseMatrix, SparseMatrix) are not registered in Kryo. So there are some performance issues for those object serialization or deserialization.
