Sameer Farooqui leads this new 3-day
training program offered by Databricks and
O’Reilly Media at Strata + Hadoop World
events worldwide.
Participants will also receive limited free-tier
accounts on Databricks Cloud.
Note: this sold out early, so if you want to
attend it at Strata EU, sign up quickly!

6. Spark Developer Certification
Fri Feb 20, 2015 10:40am-12:40pm
• http://oreilly.com/go/sparkcert
• defined by Spark experts @Databricks
• assessed by O’Reilly Media
• establishes the bar for Spark expertise

7. • 40 multiple-choice questions, 90 minutes
• mostly structured as choices among code blocks
• expect some Python, Java, Scala, SQL
• understand theory of operation
• identify best practices
• recognize code that is more parallel, less
memory constrained
!
Overall, you need to write Spark apps in practice

9. Keynote: New Directions for Spark in 2015
Fri Feb 20 9:15am-9:25am

public/schedule/detail/39547
As the Apache Spark userbase grows, the developer community is working
to adapt it for ever-wider use cases. 2014 saw fast adoption of Spark in the
enterprise and major improvements in its performance, scalability and
standard libraries. In 2015, we want to make Spark accessible to a wider
set of users, through new high-level APIs for data science: machine learning
pipelines, data frames, and R language bindings. In addition, we are defining
extension points to let Spark grow as a platform, making it easy to plug in
data sources, algorithms, and external packages. Like all work on Spark,
these APIs are designed to plug seamlessly into Spark applications, giving
users a unified platform for streaming, batch and interactive data processing.

A Brief History: Functional Programming for Big Data
circa late 1990s:
explosive growth e-commerce and machine data
implied that workloads could not fit on a single
computer anymore…
notable firms led the shift to horizontal scale-out
on clusters of commodity hardware, especially
for machine learning use cases at scale

17. Developed in 2009 at UC Berkeley AMPLab, then
open sourced in 2010, Spark has since become
one of the largest OSS communities in big data,
with over 200 contributors in 50+ organizations
spark.apache.org
“Organizations that are looking at big data challenges –
including collection, ETL, storage, exploration and analytics –
should consider Spark for its in-memory performance and
the breadth of its model. It supports advanced analytics
solutions on Hadoop clusters, including the iterative model
required for machine learning and graph analysis.”
