SPRKSCL1156

org.apache.spark.sql.functions.degrees

Message: org.apache.spark.sql.functions.degrees has a workaround, see documentation for more info

Category: Warning

Description

This issue appears when the SMA detects a use of the org.apache.spark.sql.functions.degrees function, which has a workaround.

Scenario

Input

Below is an example of the org.apache.spark.sql.functions.degrees function, first used with a column name as an argument and then with a column object.

val df = Seq(math.Pi, math.Pi / 2, math.Pi / 4, math.Pi / 6).toDF("radians")
val result1 = df.withColumn("degrees", degrees("radians"))
val result2 = df.withColumn("degrees", degrees(col("radians")))

Output

The SMA adds the EWI SPRKSCL1156 to the output code to let you know that this function is not fully supported by Snowpark, but it has a workaround.

val df = Seq(math.Pi, math.Pi / 2, math.Pi / 4, math.Pi / 6).toDF("radians")
/*EWI: SPRKSCL1156 => org.apache.spark.sql.functions.degrees has a workaround, see documentation for more info*/
val result1 = df.withColumn("degrees", degrees("radians"))
/*EWI: SPRKSCL1156 => org.apache.spark.sql.functions.degrees has a workaround, see documentation for more info*/
val result2 = df.withColumn("degrees", degrees(col("radians")))

Recommended fix

Snowpark has an equivalent degrees function that receives a column object as an argument. For that reason, the Spark overload that receives a column object as an argument is directly supported by Snowpark and does not require any changes.

For the overload that receives a string argument, you can convert the string into a column object using the com.snowflake.snowpark.functions.col function as a workaround.

val df = Seq(math.Pi, math.Pi / 2, math.Pi / 4, math.Pi / 6).toDF("radians")
val result1 = df.withColumn("degrees", degrees(col("radians")))
val result2 = df.withColumn("degrees", degrees(col("radians")))
