Fetching Spark Maven dependencies
The Maven coordinates are a combination of groupId, artifactId and
version. The groupId and artifactId are the same as for the upstream
Apache Spark project. For example, for
org.apache.spark, and artifactId is
spark-core_2.11, both the same as the upstream project.
The version is different for the Cloudera packaging: see the release notes
for the exact name depending on which release you are using.
