Set up HADOOP_HOME variable in windows

Question

I am trying to use Spark along with Hadoop in my Windows 8. However no matter what my code is, I receive this error:

15/08/25 19:29:58 ERROR Shell: Failed to locate the winutils binary in the hadoop binary path

As you can see:

null\bin\winutils.exe

The hadoop home path is null. I tried to set HADOOP_HOME as an environment variable but that did not resolve this issue.

Answer 1

I managed to resolve this problem using the following part of code in the begining:

import sys
import os

os.environ['HADOOP_HOME'] = "C:/Mine/Spark/hadoop-2.6.0"
sys.path.append("C:/Mine/Spark/hadoop-2.6.0/bin")

Hope this helps someone and also if anyone has a better idea, I would definitely appreciate that.
