The document discusses Hadoop and its capabilities for real-time analytics. It describes how Hadoop provides massive storage and parallel processing. It also explains the key components of Hadoop including HDFS for storage and YARN as the data operating system. The document outlines use cases for real-time analytics in various industries and demonstrates a real-time analytics application for monitoring truck driver behavior.

3. Hadoop provides
• Terabytes to Petabytes of storage on commodity hardware (HDFS)
• Massive parallel computation on enormous amount of data (YARN)
Hadoop is essentially a supercomputer for the masses!

13. Truck Demo: Real-Time Analytics
Problem:
• The only way to measure “safe driving” is through accident
occurences.
• There’s no realtime accident prevention mechanism in place
Solution:
• Use Hadoop to analyze driving violations in real-time
• Provide a UI to view to real-time violation alerts
• Provide a dashboard to review violation reports

22. YARN General Store – The Future
• A Data Lake that has a General Store to continually serve you….
– App Store – YARN Ready Applications
– Data Store – Where do I get the interesting data…Weather, Geo, ..etc.
– View Store – How do I get UI’s to the cluster
– Processing Store – Falcon, Pig...etc. for “standard” data sets or common “processing
patterns”

Security needs are changing
• YARN unlocks the data lake
• Multi-tenant: Multiple applications for data access
• Changing and complex compliance environment
• ETL of non-sensitive data can yield sensitive data
Summer 2014
65% of clusters host
multiple workloads
Fall 2013
Largely silo’d deployments
with single workload clusters
5 areas of security focus
