Answer 1

This is a simple 4 step process:

For Spark 2.0+:

1. Download Hadoop for Windows / Winutils

2. Add this to your code (before SparkSession initialization):

   if(getOS()=="windows"){
       System.setProperty("hadoop.home.dir", "C:/Users//winutils-master/hadoop-2.7.1"); 
   }   
   

3. Add this to your spark-session (You can change it to C:/Temp instead of Desktop).

   .config("hive.exec.scratchdir","C:/Users//Desktop/tmphive")
   

4. Open cmd.exe and run:

   "path\to\hadoop-2.7.1\bin\winutils.exe" chmod 777 C:\Users\\Desktop\tmphive
