The Power of Hadoop to Transform Business


My Background

University, Startups– Aptex, MusicMatch, ID Analytics, Veoh– big data since before it was big

Open source– even before the internet– Apache Hadoop, Mahout, Zookeeper, Drill– bought the beer at first HUG

MapR Founding member of Apache Drill


MapR Technologies

Silicon Valley Startup– Top investors– Top technical and management team• Google, Microsoft, EMC, NetApp, Oracle

Enterprise quality distribution for Hadoop

Many extensions to basic Hadoop function Strong supporter of Apache Drill


Philosophy First

What is History?


The study of the past

(what came before now)


What is the future?

(it comes after now)


But the future also has a past!


Do you remember the future?


Some things

turned out as

expected


Many things are different!


Hadoop has a history


Hadoop also has a

future


The Old Future of Hadoop

Map-reduce and HDFS– more and more, but not really different

Eco-system additions– Simpler programming (Hive and Pig)– Key-value store– Ad hoc query

Stands apart from other computing– Required by HDFS and other limitations


The New Future of Hadoop

Real-time processing– Combines real-time and long-time

Integration with traditional IT– No need to stand apart

Integration with new technologies– Solr, Node.js, Twisted all should interface directly

Fast and flexible computation– Drill logical plan language


Example #1Search Abuse


History matrix

One row per user

One column per thing


Recommendation based on cooccurrence

Cooccurrence gives item-item mapping

One row and column per thing


Cooccurrence matrix can also be implemented as a search index


SolRIndexerSolR

IndexerSolrindexing

Cooccurrence(Mahout)

Item meta-data

Indexshards

Complete history


SolRIndexerSolR

IndexerSolrsearchWeb tier

Item meta-data

Indexshards

User history


Objective Results

At a very large credit card company

History is all transactions, all web interaction

Processing time cut from 20 hours per day to 3

Recommendation engine load time decreased from 8 hours to 3 minutes


Example #2Web

Technology


Fast analysis(Storm)

Analytic output

Real-timedata

Raw logs


Large analysis(map-reduce)

Analytic output Raw logs


Presentation tier (d3 + node.js)

Analytic output

Browser query

Raw logs


Objective Results

Real-time + long-time analysis is seamless

Web tier can be rooted directly on Hadoop cluster

No need to move data

Design Principles

Flexible• Pluggable query languages• Extensible execution engine• Pluggable data formats

• Column-based and row-based• Schema and schema-less

• Pluggable data sources

Easy• Unzip and run• Zero configuration• Reverse DNS not needed• IP addresses can change• Clear and concise log messages

Dependable• No SPOF• Instant recovery from crashes

Fast• C/C++ core with Java support

• Google C++ style guide• Min latency and max throughput

(limited only by hardware)


Simple Architecture


Standard Interfaces


query:[ { op:"sequence", do:[ { op: "scan", memo: "initial_scan", ref: "donuts", source: "local-logs", selection: {data: "activity"} }, { op: "transform", transforms: [ { ref: "donuts.quanity", expr: "donuts.sales”} ] }, { op: "filter", expr: "donuts.ppu < 1.00" }, …

Logical Plan Syntax:


Logical Streaming Example

{ @id: <refnum>, op: “window-frame”, input: <input>, keys: [ <name>,... ], ref: <name>, before: 2, after: here}

0 1 2 3 4

0 0 10 1 2 1 2 32 3 4


Logical Plan


Execution Plan


Representing a DAG

{ @id: 19, op: "aggregate", input: 18, type: <simple|running|repeat>, keys: [<name>,...], aggregations: [ {ref: <name>, expr: <aggexpr> },... ]}


Non-SQL queries

The future is not what we thought it would be


It is better!
