Apache SparkThe Emerging Platform for Distributed Analytics

July 2014

Thomas W. Dinsmore

What is Apache Spark?• Distributed in-memory analytics engine

• Runs in standalone clusters or Hadoop

• Fully compatible with Hadoop storage APIs

• Runs under YARN

• Top-level Apache project

• Supported in all major Hadoop distros

• Open source and vendor neutral

News cascade starting late last year.

What problems does Spark solve?

Problem #1: MapReduce I/O sandbags runtime for advanced analytics.

Compute Store

Must persist results after each pass through data

Advanced analytics often requires multiple passes through data

Hadoop Storage

Spark Vision: Distributed in-memory platform

Compute

Intermediate results stay in memory.

100X performance improvement for iterative algorithms.

How important is Spark?

Mike Olson, Cloudera:

“The leading candidate for ‘successor to MapReduce’ today is Apache Spark.”

Thomas W. Dinsmore

M.C. Srivas, MapR:

“We believe Spark on Hadoop is a game changer for any business.”

Thomas W. Dinsmore

Ben Lorica, O’Reilly Media:

“The number of companies that are using Spark in production has exploded over the last year.”

Spark’s Key Capabilities

Spark 1.0 Machine Learning• Linear Regression

• Logistic Regression

• Linear Support Vector Machine

• Regularization

• Decision Trees

• Naive Bayes

• Alternating Least Squares

• K-Means Plus-Plus

• Singular Value Decomposition

• Principal Components Analysis

• Stochastic Gradient Descent

• L-BFGS

Spark project expects to double supported techniques in 1.1 (August 2014).Thomas W. Dinsmore

Spark SQL• Currently most active project

• Supports fast interactive queries

• Hive-compatible

• Works with Hive data

• Runs unmodified queries

• Roadmap to support more formats

• Will absorb Shark project

Thomas W. Dinsmore

Spark Streaming• Supports analysis of data streams in real time

• Unifies streaming and batch data

• Integrates with popular data sources:

• HDFS

• Flume

• Kafka

• Twitter

• Easy to use

• Fault tolerant

Thomas W. Dinsmore

Spark Graph Analytics

• Currently Alpha release

• Unifies graph-parallel and data-parallel computing under single API

• Performance parity with Giraph

• Replaces Spark Bagel (Pregel on Spark)

Thomas W. Dinsmore

Spark PerformanceMachine Learning

• 100x faster than MapReduce

Queries (Shark) !

• Comparable to Impala

• 100x faster than Hive

!

Streaming

• 2X throughput of Storm

Graph (GraphX) !

• Comparable to Giraph

• 10X faster than MapReduce
