Big Data Essentials Bootcamp


Big Data needs proper tools and skills, and this workshop brings you “from zero to hero,” that is, provides the student with the necessary knowledge of Hadoop, Spark, and NoSQL. With these three fundamentals, you will be able to build systems processing massive amounts of data, in archival, batch, interactive and finally real-time manner. The workshop also lays foundations for proper analytics, allowing to extract insights from data.

What You Will Learn:

  • Hadoop: HDFS, MapReduce, Pig, Hive
  • Spark: Spark core, SparkSQL, Spark Java API, Spark Streaming
  • NoSQL: Cassandra/HBase architecture, Java API, drivers, data modeling

Audience: developers

Duration: 5 days

Format: lectures (50%) and hands-on labs (50%).


  • comfortable with Java programming language (most programming exercises are in java)
  • comfortable in Linux environment (be able to navigate Linux command line, edit files using vi / nano)

Lab environment

Zero Install: There is no need to install Hadoop, Spark, etc. software on students’ machines! Working clusters and environments will be provided for students.

Students will need the following

  • an SSH client (Linux and Mac already have ssh clients, for Windows Putty is recommended)
  • a browser to access the cluster
