I have to get the datatype and do a case match and convert it to some required format. But the usage of org.apache.spark.ml.linalg.VectorUDT is showing VectorUDT is private. Also I specifically need to use org.apache.spark.ml.linalg.VectorUDT and not org.apache.spark.mllib.linalg.VectorUDT. Can someone suggest how to go about this?

org.apache.spark.ml.linalgtypes you should specify schema usingorg.apache.spark.ml.linalg.SQLDataTypeswhich provide singleton instances of the privateUDTtypes:MatrixTypefor matrices (org.apache.spark.ml.linalg.Matrix).VectorTypefor vectors (org.apache.spark.ml.linalg.Vector).
