The Cloudera Technology Day was held in Washington, DC on March 16, 2016 at the Arena Stage at the Mead Center for American Theater. This technical program was designed to provide current and continuing professional education for industry and government professionals in the mid-Atlantic region who have been using, or aspired to use, Apache Hadoop-based modern data infrastructure.

The agenda featured an opening session by Doug Cutting, Cloudera chief architect and creator of several leading open source projects, including Apache Hadoop, Apache Avro, and Apache Lucene. In addition, the intensive one-day program featured expert briefings on:
  • Fast Analytics on Fast Data
    Including the latest on Apache Kudu (incubating), the new columnar data store for the Hadoop ecosystem
  • Risk Management for Data 
    Attendees learned how to orchestrate modern security architecture for Hadoop under the Cloudera Security Maturity Model
  • Intuitive Real-Time Analytics
    Speakers explored the integrated capabilities of Apache Solr and Hadoop for enabling search-based analytics
  • Advanced Analytics with Apache Spark
    Attendees heard an overview of the real-world applications of Spark for machine-learning use cases

Following a networking lunch, participants attended in-depth tutorials on secure architectures for Hadoop clusters and best practices for running the Hadoop stack in production.

Registration and Networking Breakfast

8:30 – 9:00 AM

Keynote -- From MapReduce to Spark: An Ecosystem Evolves SLIDES

Hadoop was the first software to permit affordable use of petabytes. In the decade since Hadoop was introduced, many other projects have been created around the Hadoop Distributed File System (HDFS) storage layer and its MapReduce processing engine, forming a rich software ecosystem. In this keynote, Doug Cutting will explain how Apache Spark provides a second-generation processing engine that greatly improves on MapReduce, and why this transition provides an example of an evolutionary pattern in the data ecosystem that gives it long-term strength.

Doug Cutting, Chief Architect, Cloudera

9:00 – 9:40 AM

Apache Kudu (Incubating): New Hadoop Storage for Fast Analytics on Fast Data SLIDES

The Hadoop ecosystem has improved real-time access capabilities recently, narrowing the gap with relational database technologies. However, gaps remain in the storage layer that complicate the transition to Hadoop-based architectures. In this session, the presenter will describe these gaps and discuss the tradeoffs between real-time transactional access and fast analytic performance from the perspective of storage engine internals. The session also will cover Kudu (currently in beta), the new addition to the open source Hadoop ecosystem with outof-the-box integration with Apache Spark and Apache Impala (incubating), that achieves fast scans and fast random access from a single API.

Todd Lipcon, Software Engineer, Cloudera / Kudu Founder

9:40 – 10:20 AM

Risk Management for Data: Secured and Governed SLIDES

Protecting enterprise data is an increasingly complex challenge given the diversity and sophistication of threat actors and their cyber-tactics. In this session, participants will hear a comprehensive introduction to Hadoop Security, including the “three A’s” for secure operating environments: Authentication, Authorization, and Audit. In addition, the presenter will cover strategies to orchestrate data security, encryption, and compliance, and will explain the Cloudera Security Maturity Model for Hadoop. Attendees will leave with a greater understanding of how effective INFOSEC relies on an enterprise big data governance and risk management approach.

Eddie Garcia, Chief Security Architect, Cloudera

10:20 – 10:35 AM

Networking Break

10:35 – 11:15 AM

Intuitive Real-Time Analytics with Search SLIDES

Text-based search recently has become a critical part of the Hadoop stack, and has emerged as one of the highest-performing solutions for big data analytics. In this session, attendees will learn about the new analytics capabilities in Apache Solr that integrate full-text search, faceted search, statistics, and grouping to provide a powerful engine for enabling next-generation big data analytics applications.

Eva Andreasson, Director Product Management, Cloudera

11:15 – 11:55 AM

Introduction to Machine Learning on Apache Spark MLlib SLIDES

Spark MLlib is a library for performing machine learning and associated tasks on massive datasets. With MLlib, fitting a machine-learning model to a billion observations can take only a few lines of code, and leverage hundreds of machines. This talk will demonstrate how to use Spark MLlib to fit an ML model that can predict which customers of a telecommunications company are likely to stop using their service. It will cover the use of Spark's DataFrames API for fast data manipulation, as well as ML Pipelines for making the model development and refinement process easier.

1:00 – 4:00 PM Track A:

A Practitioner’s Guide to Securing Your Hadoop Cluster

Why do many Hadoop clusters lack basic security controls? In part because some security features are relatively new and Hadoop security can be complex and daunting. Participants in this tutorial will be led through the process of securing a Hadoop cluster. The instructors will begin with a Hadoop cluster with no security and incrementally add security features related to authentication, authorization, encryption of data at rest, encryption of data in transit, and complete data governance considerations. The following topics will be covered for each of the security features above:

● Introduction: what the security feature is, what protection it provides, and best practices and recommendations
● Planning: how to enable the feature in a phased manner with the fewest growing pains and least risk
● Relevance: why it’s important (demonstrated by live attacks against a cluster without the target security feature)
● Implementation: an overview of how the implementation is performed, where are the moving parts, and potential pitfalls During this tutorial, participants will be provided a maximally secure cluster to learn from and attack. Attendees should bring a laptop to the session with Internet access and the ability to run an SSH client.

1:00 – 4:00 PM Track B:

Apache Hadoop Operations for Production Systems

Hadoop is emerging as the standard for big data processing and analytics; however, as usage of the Hadoop clusters grow, so do the demands of managing and monitoring these systems. In this tutorial, attendees will be provided an overview of the necessary phases for successfully managing Hadoop clusters, with an emphasis on production systems—from installation, to configuration management, service monitoring and troubleshooting and support integration. Participants will receive a review of tooling capabilities and learn which have been most helpful to users, as well as hear lessons learned and best practices from users who depend on Hadoop as a business-critical system. The topics to be covered include:

● Installation (hardware considerations, OS prerequisites, sanity testing, security considerations)
● Configuration (mechanics, key configurations, resource management)
● Troubleshooting (managing, troubleshooting, and debugging Hadoop clusters and applications)
● Enterprise considerations (scaling, logs, failure testing)
