This is the companion repo to my LinkedIn Learning Courses on Hadoop and Spark.

1. Learning Hadoop - link uses mostly GCP Dataproc for running Hadoop and associated libraries (i.e. Hive, Pig, Spark...) workloads
2. Cloud Hadoop: Scaling Apache Spark - link - uses GCP DataProc, AWS EMR or Databricks on AWS
3. Azure Databricks Spark Essential Training - link uses Azure with Databricks for scaling Apache Spark workloads

• Setup a Hadoop/Spark cloud-cluster on GCP DataProc or AWS EMR
  • see setup-hadoop folder in this Repo for instructions/scripts
• Setup a Hadoop/Spark dev environment
  • can use EclipseChe (on-line IDE), or local IDE
  • select your language (i.e. Python, Scala...)
• Create a GCS bucket for input/output job data
  • see example_datasets folder in this Repo for sample data files
• Use Databricks Community Edition (managed, hosted Apache Spark) - example shown below
  • uses Databricks (Jupyter-style) notebooks to connect to a small, managed Spark cluster
  • AWS or Azure editions - easier to try out on AWS
  • Sign up for free trial - link

EXAMPLES from org.apache.hadoop_or_spark.examples - link for Spark examples

• Run a Hadoop WordCount Job with Java (jar file)
• Run a Hadoop and/or Spark CalculatePi (digits) Script with PySpark or other libraries
• Run using Cloudera shared demo env
  • at https://demo.gethue.com/
  • login is user:demo, pwd:demo
