Beyond the Big Elephant

Data
Big data ecosystem is evolving and changing rapidly.
• Data grows faster than Moore’s law
• massive, unstructured, and dirty
• don’t always know what questions to answer
• Driving architectural transition
• scale up -> scale out
• compute, network, storage

Ecosystem Challenges
• Building a working data processing environment has become
a challenging and highly complex task.
• Exponential growth of the frameworks, standard libraries and
transient dependencies
• Constant flow of new features, bug fixes, and other changes
are almost a disaster
• Struggle to convert early experiments into a scalable
environment for managing data (however big)
!

Ecosystem Challenges
• Extract business value from diverse data sources and new data
types
• Deeper analytics requires users to build complex pipelines
involving ML algorithms
• Apache Mahout on Hadoop
• 25 production quality algorithms
• only 8-9 can scale over large data sets
• New use-cases require integration beyond Hadoop

Apache Hadoop
• The de-facto standard for data processing is rarely, if ever,
used in isolation.
• input comes from other frameworks
• output get consumed by other frameworks
• Good for batch processing and data-parallel processing
• Beyond Hadoop Map-Reduce
• real-time computation and programming models
• multiple topologies, mixed workloads, multi-tenancy
• reduced latency between batch and end-use services

Hadoop Ecosystem - Technology Partnerships
Jan 2013 Data, Datameer
Hadoop software distribution ties into
Active Directory, Microsoft's System
Center, and Microsoft virtualization
technologies to simplify deployment
and management.

Platform Goals
An integrated infrastructure that allows emerging technologies to
take advantage of our existing ecosystem and keep pace with end
use cases
• Consistent, compact and flexible means of integrating,
deploying and managing containerised big data applications,
services and frameworks
• Unification of data computation models: batch, interactive, and
streaming.
• Efficient resource isolation and sharing models that allow
multiple services and frameworks to leverage resources across
shared pools on demand
• Simple, Modular and Extensible

Perfection is not the immediate goal. Abstraction is
what we need

Backup Slides

Mesos - mesos.apache.org
An abstracted scheduler/executor layer, to receive/consume resource
offers and thus perform tasks or run services, atop a distributed file
system (RHS by default)
• Fault-tolerant replicated master using ZooKeeper
• Scalability to 10,000s of nodes
• Isolation between tasks with Linux Containers
• Multi-resource scheduling (memory and CPU aware)
• Java, Python and C++ APIs
• scalability to 10,000s of nodes
• Primarily written in C++

Resource Manager

Spark - spark.incubator.apache.org
Unified framework for large scale data processing.
• Fast and expressive framework interoperable with Apache Hadoop
• Key idea: RDDs “resilient distributed datasets” that can automatically be rebuilt on
failure
• Keep large working sets in memory
• Fault tolerance mechanism based on “lineage”
• Unifies batch, streaming, interactive computational models
• In-memory cluster computing framework for applications that reuse working sets of data
• Iterative algorithms: machine learning, graph processing, optimization
• Interactive data mining: order of magnitude faster than disk-based tools
!
• Powerful APIs in Scala, Python, Java
• Interactive shell
