I have followed this solution -- https://qnalist.com/questions/4994960/run-spark-unit-test-on-windows-7 but still not able to resolve this issue

I am running simple spark program in Scala IDE on windows 7, I don't have hadoop installed on my windows.
I followed below steps but still why I am failing?
1. I have copied winutils.exe to C:\winutil\bin
from https://social.msdn.microsoft.com/forums/azure/en-US/28a57efb-082b-424b-8d9e-731b1fe135de/please-read-if-experiencing-job-failures?forum=hdinsight
2. I have set my environment variable as HADOOP_HOME = C:\winutil and in PATH=C:\winutil\bin
3. Below is my spark code
object WordCount extends App {
val conf = new SparkConf()
System.setProperty("hadoop.home.dir","C:\\winutil\\")
val sc=new SparkContext("local","WordCount",conf)
val test=sc.textFile("food.txt")
test.flatMap(line=>line.split(" "))
.map(word => (word,1))
.reduceByKey(_+_)
.saveAsTextFile("food_output.txt")
}

> I'm trying to run some transformation on Spark, it works fine on cluster (YARN, linux machines). However, when I'm trying to run it on local machine (Windows 7) under unit test, I got errors (I don't use Hadoop, I'm read file from local filesystem):

> It's happened because Hadoop config is initialized each time when spark context is created regardless is hadoop required or not.
> I propose to add some special flag to indicate if hadoop config is required (or start this configuration manually)
