SPRKSCL1115

org.apache.spark.sql.functions.round

This issue code has been deprecated since Spark Conversion Core Version 4.6.0

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

Scenario

Input

Below is an example of the org.apache.spark.sql.functions.round function that generates this EWI.

val df = Seq(3.9876, 5.673, 8.1234).toDF("value")
val result1 = df.withColumn("rounded_value", round(col("value")))
val result2 = df.withColumn("rounded_value", round(col("value"), 2))

Output

The SMA adds the EWI SPRKSCL1115 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(3.9876, 5.673, 8.1234).toDF("value")
/*EWI: SPRKSCL1115 => org.apache.spark.sql.functions.round has a workaround, see documentation for more info*/
val result1 = df.withColumn("rounded_value", round(col("value")))
/*EWI: SPRKSCL1115 => org.apache.spark.sql.functions.round has a workaround, see documentation for more info*/
val result2 = df.withColumn("rounded_value", round(col("value"), 2))

Recommended fix

Snowpark has an equivalent round 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 column object and a scale, you can convert the scale into a column object using the com.snowflake.snowpark.functions.lit function as a workaround.

val df = Seq(3.9876, 5.673, 8.1234).toDF("value")
val result1 = df.withColumn("rounded_value", round(col("value")))
val result2 = df.withColumn("rounded_value", round(col("value"), lit(2)))
