Hi Michael,
Please correct me if I am wrong. The error seems to originate from spark
only. Please have a look at the stack trace of the error which is as
follows:
[error] (run-main-0) java.lang.NoSuchMethodException: Cannot resolve any
suitable constructor for class org.apache.spark.sql.catalyst.expressions.Row
