Installing Apache Spark

1. Open terminal and type command brew install apache-spark and hit Enter.

2. Create a log4j.properties file. Type cd /usr/local/Cellar/apache-spark/2.3.1/libexec/conf and hit Enter. Please change the version according to your downloaded version. Spark 2.3.1 is the version installed for me.

3. Type cp log4j.properties.template log4j.properties and hit Enter.

4. Edit the log4j.properties file and change the log level from INFO to ERROR on log4j.rootCategory. We are just changing the log level from INFO to ERROR only.

Download Scala IDE

• Install the Scala IDE from here.

• Open the IDE once, just to check if it's running fine. You should see panels like this;

Test it out!

1. Open terminal and go to the directory where apache-spark was installed to (such as cd /usr/local/Cellar/apache-spark/2.3.1/libexec/) and then type ls to get a directory listing.

2. Look for a text file, like README.md or CHANGES.txt.

3. Type command spark-shell and hit Enter.

4. At this point you should see a scala> prompt. If not, double check the steps above.

5. Type val rdd = sc.textFile("README.md") or whatever text file you’ve found and hit Enter. You have just created a rdd of readme text file. Now type rdd.count() and hit Enter to count the number of lines in text file.

6. You should get a count of number of lines in that file! Congratulations, you just ran your first Spark program! Don't worry about the commands, I will explain them.
