SPRKSCL1160

org.apache.spark.sql.functions.sum

This issue code has been deprecated since Spark Conversion Core 4.1.0

Message: org.apache.spark.sql.functions.sum 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.sum function, which has a workaround.

Scenario

Input

Below is an example of the org.apache.spark.sql.functions.sum function that generates this EWI. In this example, the sum function is used to calculate the sum of selected column.

val df = Seq("1", "2", "3", "4", "5").toDF("elements")
val result1 = sum(col("elements"))
val result2 = sum("elements")

Output

The SMA adds the EWI SPRKSCL1160 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("1", "2", "3", "4", "5").toDF("elements")
/*EWI: SPRKSCL1160 => org.apache.spark.sql.functions.sum has a workaround, see documentation for more info*/
val result1 = sum(col("elements"))
/*EWI: SPRKSCL1160 => org.apache.spark.sql.functions.sum has a workaround, see documentation for more info*/
val result2 = sum("elements")

Recommended fix

Snowpark has an equivalent sum 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("1", "2", "3", "4", "5").toDF("elements")
val result1 = sum(col("elements"))
val result2 = sum(col("elements"))
