Overview


What is Hadoop?
 What is Hadoop?
– Distributed computing paradigm
– File system – HDFS
– Processing framework –Map Reduce
– Languages – PIG, HIVE
– Key Value Store – Hbase
 Why is it important?
– BIG Data is everywhere
– BIG Data is mostly unstructured
– Need affordable, scalable no-sql processing


Analytics Workbench - Motivation
 Open source
– Hadoop industry is nascent
– BIG Data development needs scale

 Greenplum
– Innovation & Experimentation platform
– Contribute to the community
– GPDB & GPHD - Mixed mode environment

Peek @ the Cluster


Cluster Statistics
Largest cluster for Apache Hadoop validation!

 # Of Physical Hosts : > 1,000 (> 10,000 with VMs)
 # Of Racks : 54 (50 just for the DataNodes)
 # Of Processors : > 24,000
 Amount Of RAM : > 48TB
 Amount of Disk Capacity : > 24PB
– “Equivalent to nearly half of the entire written works of
mankind from the beginning of recorded history”

Initial Use Cases
 Apache Hadoop Validation
 Mellanox UDA
 Terasort Benchmark


Apache Hadoop Validation
 Purpose
– Run Apache Hadoop Validation at Scale
– Validate cluster configuration

 Various Configurations Validated
– Standard Out Of The Box Configs
– Configs Modified For IO Intensive Processing

Apache Hadoop Findings
 Apache BigTop for integration tests
 Functional validation passed as expected

 Next Steps
– Identify integration cases
– Contribute back to BigTop
– Stabilize Hadoop 0.23


Mellanox UDA - Overview
 RDMA in Hadoop Shuffle stage
 Register Map & Reduce task buffer
 Hadoop JT for Task completion
 cp sorted maptask o/p  reduce i/p
 Perform in-memory merge @reduce
 Avoid disk spills for large inputs
 Reduce CPU load for sort & merge
 GP + Mellanox collaboration
– Open Sourcing UDA


Mellanox UDA Preliminary Results
 Preliminary UDA results provided by Mellanox
 Show improvement with UDA vs Vanilla Hadoop.
 Better CPU utilization
 Reduced execution time

 Next Steps
– Run on Analytics Workbench schedule for June 2012
– Configuration on the workbench to turn it on/off


TeraSort Benchmark
 Industry standard benchmark
 Good validation of configuration
 3 Steps
– Teragen – Generate 1TB of data
– Terasort – Sort generated data
– Teravalidate – Validate the sort
 Measure time for each step
