Hello All,
I'm working through the Data Science with Scala course on Big Data
University and it is not updated to work with Spark 2.0, so I'm adapting
the code as I work through it, however I've finally run into something
that is over my head. I'm new to Scala as well.
When I run this code
(https://gist.github.com/jmwoloso/a715cc4d7f1e7cc7951fab4edf6218b1) I
get the following error:
`java.lang.ClassCastException: org.apache.spark.ml.linalg.DenseVector
cannot be cast to org.apache.spark.mllib.linalg.Vector`
I believe this is occurring at line 107 of the gist above. The code
starting at this line (and continuing to the end of the gist) is the
current code in the course.
If I try to map to any other class type, then I have problems with the
`Statistics.corr(rddVec)`.
How can I convert `rddVec` from an `ml.linalg.DenseVector` into an
`mllib.linalg.Vector` for use with `Statistics`?
Thanks!
-Jason
