SPRKSCL1123
org.apache.spark.sql.functions.cos
Message: org.apache.spark.sql.functions.cos 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.cos function, which has a workaround.
Scenario
Input
Below is an example of the org.apache.spark.sql.functions.cos
function, first used with a column name as an argument and then with a column object.
val df = Seq(0.0, Math.PI / 4, Math.PI / 2, Math.PI).toDF("angle_radians")
val result1 = df.withColumn("cosine_value", cos("angle_radians"))
val result2 = df.withColumn("cosine_value", cos(col("angle_radians")))
Output
The SMA adds the EWI SPRKSCL1123
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(0.0, Math.PI / 4, Math.PI / 2, Math.PI).toDF("angle_radians")
/*EWI: SPRKSCL1123 => org.apache.spark.sql.functions.cos has a workaround, see documentation for more info*/
val result1 = df.withColumn("cosine_value", cos("angle_radians"))
/*EWI: SPRKSCL1123 => org.apache.spark.sql.functions.cos has a workaround, see documentation for more info*/
val result2 = df.withColumn("cosine_value", cos(col("angle_radians")))
Recommended fix
Snowpark has an equivalent cos 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(0.0, Math.PI / 4, Math.PI / 2, Math.PI).toDF("angle_radians")
val result1 = df.withColumn("cosine_value", cos(col("angle_radians")))
val result2 = df.withColumn("cosine_value", cos(col("angle_radians")))
