Agenda
• OpenStack Data Processing Overview
• EDP Architecture & Technical Concepts
• Live Demo
Elastic Data Processing
• EDP - API for executing MapReduce jobs on Hadoop clusters (similar to AWS EMR)• Supported data sources: Swift, HDFS, Ceph• Supported job types: Java actions,
MapReduce, MapReduce.Streaming, Pig, Hive• Oozie for Hadoop jobs workflow management
• Supports both Hadoop 1 & 2• Job executions on transient clusters
EDP Use Cases
• Simplified task executions. You don’t need to know Hadoop!
• Bursty workload: ad-hoc queries requiring a significant resource only for short time period
• Utilization of free IaaS capacity for Hadoop tasks

Agenda

EDP BigPetStore Demo
BigPetStore is now part of Apache BigTop• Test/demo laboratory for all things Hadoop
• Actively developed with integration testing
• Generates and processes data of arbitrary size
• git clone git://git.apache.org/bigtop.git
• Filed under bigtop/bigtop-bigpetstore
EDP BigPetStore Demo
What are we going to do?
• Generate 1M records of pet supply purchases• Clean the data (“dirty CSV”)• Extract cumulative counts by state• Demonstrates Sahara EDP objects
• Job Binaries• Jobs (Java and Pig)• Data Sources

What Next for EDP
Potential Areas for Development within EDP
• Pluggable Job Execution Model• Allows Sahara to run jobs with additional execution engines• Current Oozie offerings become one of multiple options
• Expand Capabilities via Oozie• Support upload of user-written Oozie workflows• Support for coordinated jobs
• Enhanced Usability• Better Error Reporting• User Experience (UI, CLI, API)
