I'm trying to convert a dataframe to dataset using the syntax
case class Schema(...)
val ds = df.as[Schema]
So my code looks like
case class Rule(rule_on: String, rule_operator: String, rule_value: Int, rule_name: String)
val rules_ds = rules_df
.select("rule_on", "rule_operator", "rule_value", "rule_name")
.as[Rule]
But eclipse is highlighting .as[Rule]
as error. Screen shots of the same as below.
How to resolve this issue? I know its not a Scala issue, as it works on command line.
Environment (as in Eclipse):
As suggested by Raphael Roth (in comments) I defined case class outside main method and it works like charm.
Also other solution (without using case class) is to typecast the dataframe to dataset as below
import org.apache.spark.sql._
val ds: Dataset[Row] = df
The above solution was taken from here
