		1) Java	<br />
		Make sure Java version is >= 1.8 and JAVA_HOME environment variable is set:
		{% highlight bash %} 
java -version 
export JAVA_HOME="$(/usr/libexec/java_home)"{% endhighlight %}

		2) Spark <br />
		Download Spark from <a href="https://spark.apache.org/downloads.html">https://spark.apache.org/downloads.html</a> and move to home directory, and extract. Also, set environment variables to point to the extracted directory
		{% highlight bash %} 
export SPARK_HOME="$HOME/spark-2.1.0-bin-hadoop2.7"
export HADOOP_HOME=$SPARK_HOME
export SPARK_LOCAL_IP=127.0.0.1{% endhighlight %}

		3) Python and Jupyter <br />
		Download and install Anaconda Python 3+ from <a href="https://www.anaconda.com/distribution/#download-section">https://www.anaconda.com/distribution/#download-section</a> (includes jupyter, and pip)
		{% highlight bash %}

		<div id="prerequisite-tabs-2">
		1) Java <br />
                Make sure Java version is >= 1.8. Also, set JAVA_HOME environment variable and include %JAVA_HOME%\bin in the environment variable PATH:
                {% highlight bash %} 
java -version  
ls "%JAVA_HOME%"{% endhighlight %}

                2) Spark <br />
                Download Spark from <a href="https://spark.apache.org/downloads.html">https://spark.apache.org/downloads.html</a> and extract. Set the environment variable SPARK_HOME to point to the extracted directory. <br />
		
		3) Install winutils <br />
- Download winutils.exe from <a href="http://github.com/steveloughran/winutils/raw/master/hadoop-2.6.0/bin/winutils.exe">http://github.com/steveloughran/winutils/raw/master/hadoop-2.6.0/bin/winutils.exe</a>  <br />
- Place it in c:\winutils\bin <br />
- Set environment variable HADOOP_HOME to point to c:\winutils <br />
- Add c:\winutils\bin to the environment variable PATH. <br />
- Finally, modify permission of hive directory that will be used by Spark and check if Spark is correctly installed:

                {% highlight bash %} 
winutils.exe chmod 777 /tmp/hive
%SPARK_HOME%\bin\spark-shell
%SPARK_HOME%\bin\pyspark --master local[*] --driver-memory 8G{% endhighlight %}
