Dear Developers:
Here is a bug in org.apache.spark.ml.linalg.*:
Class Vector, Vectors are not included in org.apache.spark.ml.linalg.*,
but they are used in VectorAssembler.scala as follows:
import org.apache.spark.ml.linalg.{Vector, Vectors, VectorUDT}
Therefore, bug was reported when I was using VectorAssembler.
Since org.apache.spark.mllib.linalg.* contains the class {Vector, Vectors,
VectorUDT}, I rewrote VectorAssembler.scala as XVectorAssembler.scala by
mainly changing "import org.apache.spark.ml.linalg.{Vector, Vectors,
VectorUDT}" to
"import org.apache.spark.mllib.linalg.{Vector, Vectors, VectorUDT}"
But bug occured as follows:
" Column v must be of type org.apache.spark.ml.linalg.VectorUDT@3bfc3ba7
but was actually org.apache.spark.mllib.linalg.VectorUDT@f71b0bce "
Would you please help fix the bug?
Thank you very much!
Best regards
