Hadoop Up There, Down Here...Everywhere!
Dev / Test BI / ML
IoT Apps
On-Premises

Use Cases Where?
Active Archive / Compliance Reporting Sensitive data = “down here”; “up there” valid for many
scenarios
ETL / Data Warehouse Optimization
Usually has “down here” gravity; DW in cloud is changing
that
Smart Meter Analysis Data typically flows “up there”
Single View of Customer
May have “down here” gravity; unless you’re using SaaS
apps
Supply Chain Optimization May have heavy “down here” gravity
New Data for Product Management “Up there” could be considered for many scenarios.
Vehicle Data for
Transportation/Logistics
Why not “up there”?
Vehicle Data for Insurance
May have “down here” gravity (ex. join with existing risk
data)
Anywhere? Up There or Down Here?

Deployment
Challenges & Requirements

Deployment challenges
● Infrastructure is different everywhere
○ e.g. Each cloud provider has their own API
○ e.g. Each provider has different networking methods
● OS/images are different everywhere
● How to do service discovery?
● How to dynamically scale/manage?
See prior operations workshops

- Infrastructure
- Operating System
- Environment Prepared (see docs)
- Ambari Agent/Server installed & registered
- Deploy HDP Cluster
- Ambari Blueprints or Cluster Wizard
- Ongoing configuration/management
Deployment requirements

Options for Automation
- Many combinations of tools
- e.g. Foreman, Ansible, Chef, Puppet, docker-ambari,
shell scripts, CloudFormation, …
- Provider specific
- Cisco UCS, Teradata, HP, Google’s bdutil, …
- Docker with Cloudbreak
Using Ambari with all of the above!

https://github.com/seanorama/ambari-bootstrap/
Demo: Basic script-based example

https://github.com/seanorama/ambari-bootstrap
Requirements:
● Infrastructure prepped (see HDP docs)
● Nodes with RedHat EL or CentOS 6 systems
● HDFS paths mounted (see HDP docs)
● sudo or root access
ambari-bootstrap

After Ambari deployment
● (optional) Configure local YUM/APT repos

Docker is a “Shipping Container” System for Code
Production Cluster
Customer Data Center
An engine that enables any payload to be
encapsulated as a lightweight, portable,
self-sufficient container

Docker
• Container based virtualization
• Lightweight and portable
• Build once, run anywhere
• Ease of packaging applications
• Automated and scripted
• Isolated

Why Is Docker So Exciting?
For Developers:
Build once…run anywhere
• A clean, safe, and portable runtime
environment for your app.
• No missing dependencies, packages etc.
• Run each app in its own isolated container
• Automate testing, integration, packaging
• Reduce/eliminate concerns about
compatibility on different platforms
• Cheap, zero-penalty containers to deploy
services
For DevOps:
Configure once…run anything
• Make the entire lifecycle more efficient,
consistent, and repeatable
• Eliminate inconsistencies between SDLC
stages
• Support segregation of duties
• Significantly improves the speed and
reliability of CICD
• Significantly lightweight compared to VMs

More Technical Explanation
WHY WHA
T
• Run on any LINUX
• Regardless of kernel version (2.6.32+)
• Regardless of host distro
• Physical or virtual, cloud or not
• Container and host architecture must match
• Run anything
• If it can run on the host, it can run in the
container
• i.e. if it can run on a Linux kernel, it can run
• High Level—It’s a lightweight VM
• Own process space
• Own network interface
• Can run stuff as root
• Low Level—It’s chroot on steroids
• Container=isolated processes
• Share kernel with host
• No device emulation (neither HVM nor PV)
from host)

Cloudbreak
Tool for Provision and Managing Hadoop Clusters In The
Cloud

Cloudbreak
• Developed by SequenceIQ
• Open source with Apache 2.0
license [ Apache project soon ]
• Cloud and infrastructure
agnostic, cost effective Hadoop
As-a-Service platform API.
• Elastic – can spin up any number
of nodes, add/remove on the fly
• Provides full cloud lifecycle
management post-deployment

Key Features of Cloudbreak
Elastic
• Enables provisioning an
arbitrary node Cluster
• Enables (de)
commissioning nodes
from Cluster
• Policy and time based
based scaling of cluster
Flexible
• Declarative and flexible
Hadoop cluster creation
using blueprints
• Provision to multiple
public cloud providers or
Openstack based private
cloud using same
common API
• Access all of this
functionality through rich
UI, secured REST API or
automatable Shell
Enterprise-ready
• Supports basic, token
based and OAuth2
authentication model
• The cluster is
provisioned in a logically
isolated network
• Tracking usage and
cluster metrics

Cloudbreak
1. Pick a Blueprint
2. Choose a Cloud
3. Launch HDP!
Example Ambari Blueprints:
IoT Apps, BI / Analytics, Data Science, Dev /
Test

Cloudbreak Approach
• Use Ambari for heavy lifting
• Provisioning of Hadoop services
• Monitoring
• Use Ambari Blueprints
• Assign Host groups to physical instance types
• Public/Private Cloud provider API abstracted
• Azure/Google/Amazon/Openstack
• Run Ambari agent/server in Docker container
• Networking: docker run –net=host
• Service discovery: consul (previously serf)

cloudbreak-deployer
● https://github.com/sequenceiq/cloudbreak-deployer
Requirements:
● A Docker host (laptop, server or Cloud infrastructure)
● Resources:
○ Very little. Tested with 2GB of RAM.
Workshop: Your Own CloudBreak

Requirement: a Docker host
● OSX or Windows: http://boot2docker.io/
○ boot2docker init
○ boot2docker up
○ eval "$(boot2docker shellinit)"
○ boot2docker ssh
● Linux: Install the docker daemon
● Anywhere: docker-machine “lets you create Docker hosts on your
computer, on cloud providers, and inside your own data center”
○ Example on Rackspace:
■ docker-machine create --driver rackspace
--rackspace-api-key $OS_PASSWORD
--rackspace-username $OS_USERNAME
--rackspace-region DFW docker-rax
■ docker-machine ssh docker-rax

Install cloudbreak-deployer
https://github.com/sequenceiq/cloudbreak-deployer
● curl https://raw.githubusercontent.com/sequenceiq/cloudbreak-
deployer/master/install | sh && cbd --version
● cbd init
● cbd start
You’ll then have your own CloudBreak & Periscope server
with API and Web UI

Deploy a cluster with your CloudBreak

Documentation:
http://sequenceiq.
com/cloudbreak/#clou
dbreak-credentials
1. Add Credentials

3. Use your Cluster
Ambari available as expected
To reach your Hadoop hosts:
● SSH to Docker Host
○ Hosts arre listed in “Cloud stack description”
○ ssh cloudbreak@IPofHost
● Shell to the “ambari-agent”
container
○ sudo docker ps | grep ambari-agent
■ note the CONTAINER ID
○ sudo docker -it CONTAINERID bash
● Use the hosts as usual. e.g.:
○ hadoop fs -ls /

Swarm
• Native clustering for Docker
• Distributed container orchestration
• Same API as Docker

Swarm – How it works
• Swarm managers/agents
• Discovery services
• Advanced scheduling

Consul
• Service discovery/registry
• Health checking
• Key/Value store
• DNS
• Multi datacenter aware

Consul – How it works
• Consul servers/agents
• Consistency through a quorum (RAFT)
• Scalability due to gossip based protocol (SWIM)
• Decentralized and fault tolerant
• Highly available
• Consistency over availability (CP)
• Multiple interfaces - HTTP and DNS
• Support for watches

Apache Ambari
• Easy Hadoop cluster provisioning
• Management and monitoring
• Key feature - Blueprints
• REST API, CLI shell
• Extensible
• Stacks
• Services
• Views

Apache Ambari – How it works
• Ambari server/agents
• Define a blueprint (blueprint.json)
• Define a host mapping (hostmapping.json)
• Post the cluster create

Run Hadoop as Docker containers
HDP as Docker
Containers
via Cloudbreak
• Fully Automated Ambari Cluster installation
• Avoid GUI, use rest API only (ambari-shell)
• Fully Automated HDP installation with blueprints
• Quick installation (pre-pulled rpms)
• Same process/images for dev/qa/prod
• Same process for single/multinode
