+Spark 2.2 requires explicitly specifying extra JAR files to `spark-submit`
+in order to work with AWS. To work around this, add an additional 'packages'
+argument when submitting the job:
+
+```
+spark-submit --packages com.amazonaws:aws-java-sdk:1.7.4,org.apache.hadoop:hadoop-aws:2.7.2,com.google.guava:guava:12.0
+```
