How to install MapR M3 on Ubuntu through Ubuntu Partner Archive.

In a recent post of mine I had mentioned about the partnership between MapR and Canonical towards an initiative to make Hadoop available with Ubuntu natively through Ubuntu Partner Archive. Since, the package has been released now, I thought of showing how to get it done. Trust me it's really cool to install Hadoop by just one apt-get install :)

First things first. Open your sources.list file and add the MapR repositories into it.

deb http://package.mapr.com/releases/v2.1.2/ubuntu/ mapr optional
deb http://package.mapr.com/releases/ecosystem/ubuntu binary/

Now, update your repository.
sudo apt-get update

Note : If it throws any error regarding MapR repositories, just uncomment the lines which allow us to add software from Canonical's partner repository.

## Uncomment the following two lines to add software from #Canonical's
## 'partner' repository.
## This software is not part of Ubuntu, but is offered by #Canonical and the
## respective vendors as a service to Ubuntu users.
deb http://archive.canonical.com/ubuntu precise partner 
deb-src http://archive.canonical.com/ubuntu precise partner


Install hadoop.
sudo apt-get install mapr-single-node

1, 2, 3..and you are done. Isn't that cool?Just three easy steps and you have your brand new single node hadoop cluster in your lap. But, there are some pre-requisites and it's very important to satisfy them.

CPU : 64-bit

OS : Red Hat, CentOS, SUSE, or Ubuntu

Memory : 4 GB minimum, more in production

Disk : Raw, unformatted drives and partitions

DNS : Hostname, reaches all other nodes

Users : Common users across all nodes; Keyless ssh

Java : Must run Java

Other : NTP, Syslog, PAM

The above procedure will install following services on your machine :

CLDB : mapr-cldb

JobTracker : mapr-jobtracker

MapR Control Server : mapr-webserver

MapR Data Platform : mapr-fileserver

Metrics : mapr-metrics

NFS : mapr-nfs

TaskTracker : mapr-tasktracker

ZooKeeper : mapr-zookeeper

In order to install other hadoop projects and for further documentation you can visit the official documentation here.

I hope you found this post helpful, and as always comments and suggestions are welcome.

Hadoop+Ubuntu : The Big Fat Wedding.

Now, here is a treat for all you Hadoop and Ubuntu lovers. Last month, Canonical, the organization behind the Ubuntu operating system, partnered with MapR, one of the Hadoop heavyweights, in an effort to make Hadoop available as an integrated part of Ubuntu through its repositories. The partnership announced that MapR's M3 Edition for Apache Hadoop will be packaged and made available for download as an integrated part of the Ubuntu operating system. Canonical and MapR are also working to develop a Juju Charm that can be used by OpenStack and other customers to easily deploy MapR into their environments.

The free MapR M3 Edition includes HBase, Pig, Hive, Mahout, Cascading, Sqoop, Flume and other Hadoop-related components for unlimited production use. MapR M3 will be bundled with Ubuntu 12.04 LTS and 12.10 via the Ubuntu Partner Archive. MapR also announced that the source code for the component packages of the MapR Distribution for Apache Hadoop is now publicly available on GitHub.

MapR is the only distribution that enables Linux applications and commands to access data directly in the cluster via the NFS interface that is available with all MapR Editions. The MapR M5 and M7 Editions for Apache Hadoop, which provide enterprise-grade features for HBase and Hadoop such as mirroring, snapshots, NFS HA and data placement control, will also be certified for Ubuntu.

Now, as you get Hadoop integrated natively with Ubuntu, it's a lot easier to install it and go. No more unnecessary downloads and wacky configuration steps. And the best part is the NFS interface available with MapR's distribution that enables other Linux commands and application to access the cluster data directly. The Ubuntu/MapR package will be available through the Ubuntu Partner Archive for 12.04 LTS and 12.10 releases of Ubuntu on the official website starting from April 25, 2013.
