Introduction to Big Data Analytics using Apache Spark on HDInsights on Azure (SaaS) and/or HDP on Azure(PaaS)
This workshop will provide an introduction to Big Data Analytics using Apache Spark using the HDInsights on Azure (SaaS) and/or HDP deployment on Azure(PaaS) . There will be a short lecture that includes an introduction to Spark, the Spark components.
Spark is a unified framework for big data analytics. Spark provides one integrated API for use by developers, data scientists, and analysts to perform diverse tasks that would have previously required separate processing engines such as batch analytics, stream processing and statistical modeling. Spark supports a wide range of popular languages including Python, R, Scala, SQL, and Java. Spark can read from diverse data sources and scale to thousands of nodes.
The lecture will be followed by demo . There will be a short lecture on Hadoop and how Spark and Hadoop interact and compliment each other. You will learn how to move data into HDFS using Spark APIs, create Hive table, explore the data with Spark and SQL, transform the data and then issue some SQL queries. We will be using Scala and/or PySpark for labs.
Users have 2 options to follow along with the demo labs. You can use the:
-
Hortonworks Sandbox on a VM No data center, no cloud service and no internet connection needed! Full control of the environment. http://hortonworks.com/products/hortonworks-sandbox/#install
-
HDP 2.3.2 on Azure with Hortonworks Sandbox. Try Hortonworks Sandbox on Windows Azure. It’s free for the the first month, and there’s no need to download the VM! http://hortonworks.com/blog/hortonworks-sandbox-with-hdp-2-3-is-now-available-on-microsoft-azure-gallery/
PRE-Requisite in case we don't have internet connectivity at the location.
- Do the initial setup of the HDP sandbox. The initial root password is hadoop, but you are required to change it.
