I have a dataframe with column as String. I wanted to change the column type to Double type in PySpark.
Following is the way, I did:
toDoublefunc = UserDefinedFunction(lambda x: x,DoubleType())
changedTypedf = joindf.withColumn("label",toDoublefunc(joindf["show"]))
Just wanted to know, is this the right way to do it as while running through Logistic Regression, I am getting some error, so I wonder, is this the reason for the trouble.
