Experimental set-up to add dependencies onto spark-custom Docker images. Builds for both Debian and Alpine.

This adds the following:

• AWS Hadoop SDK JAR
  • Appends spark.hadoop.fs.s3a.impl org.apache.hadoop.fs.s3a.S3AFileSystem into spark-defaults.conf
• Google Cloud Storage SDK JAR
• MariaDB JDBC Connector JAR

Additionally, all Alpine builds have gcompat and libc6-compat installed to prevent glibc shared library related issues.

The version of AWS Java SDK is dependent on the Hadoop version. An example of how to derive this version number for Hadoop 3.1.0 is here:

https://github.com/apache/hadoop/blob/release-3.1.0-RC0/hadoop-project/pom.xml#L137

For Linux user, you can download Tera CLI v0.4 at https://github.com/guangie88/tera-cli/releases and place it in PATH.

Otherwise, you will need cargo, which can be installed via rustup.

Once cargo is installed, simply run cargo install tera-cli --version=^0.4.0.
