Unsupported literal type class scala.runtime.BoxedUnit

Question

I am trying to filter a column of a dataframe read from oracle as below

import org.apache.spark.sql.functions.{col, lit, when}

val df0  =  df_org.filter(col         


        

Answer 1

Just remove parenthesis on your function:

from:
val df0 = df_org.filter(col("fiscal_year").isNotNull())
to:
val df0 = df_org.filter(col("fiscal_year").isNotNull)

Answer 2

Try removing () in isNull() in your filter.
