SPRKPY1013

pyspark.sql.functions.acosh

Message: pyspark.sql.functions.acosh has a workaround

Category: Warning.

Description

This issue appears when the tool detects the usage of pyspark.sql.functions.acosh which has a workaround.

Scenario

Input

On this example pyspark calculates the acosh for a dataframe by using pyspark.sql.functions.acosh

from pyspark.sql import SparkSession
from pyspark.sql.functions import acosh
spark = SparkSession.builder.getOrCreate()
data = [['V1', 30],
        ['V2', 60],
        ['V3', 50],
        ['V4', 13]]

columns = ['Paremeter', 'value']
df = spark.createDataFrame(data, columns)
df_with_acosh = df.withColumn("acosh_value", acosh(df["value"]))

Output

SMA returns the EWI SPRKPY1013 over the line where acosh is used, so you can use to identify where to fix.

from snowflake.snowpark import Session

spark = Session.builder.getOrCreate()
spark.update_query_tag({"origin":"sf_sit","name":"sma","version":{"major":0,"minor":0,"patch":0},"attributes":{"language":"Python"}})
data = [['V1', 30],
        ['V2', 60],
        ['V3', 50],
        ['V4', 13]]

columns = ['Paremeter', 'value']
df = spark.createDataFrame(data, columns)
#EWI: SPRKPY1013 => pyspark.sql.functions.acosh has a workaround, see documentation for more info
df_with_acosh = df.withColumn("acosh_value", acosh(df["value"]))

Recommended fix

There is no direct "acosh" implementation but "call_function" can be used instead, using "acosh" as the first parameter, and colName as the second one.

import snowflake.snowpark as snowpark
from snowflake.snowpark import Session
from snowflake.snowpark.functions import call_function, col

spark = Session.builder.getOrCreate()
spark.update_query_tag({"origin":"sf_sit","name":"sma","version":{"major":0,"minor":0,"patch":0},"attributes":{"language":"Python"}})
data = [['V1', 30],
        ['V2', 60],
        ['V3', 50],
        ['V4', 13]]

columns = ['Paremeter', 'value']
df = spark.createDataFrame(data, columns)
df_with_acosh = df.select(call_function('ACOSH', col('value')))
