Introduction
Installing Bigtop Hadoop distribution artifacts lets you have an up and running Hadoop cluster complete with
various Hadoop ecosystem projects in just a few minutes. Be it a single node pseudo-distributed
configuration, or a fully distributed cluster, just make sure you install the packages, install the JDK,
format the namenode and have fun! If Bigtop is not supported on your OS, you can install one of the supported 64-bit OSes
on a virtual machine. There is known issues with 32-bit OSes.

Make sure to grab the repo file:
No Format
wget -O /etc/yum.repos.d/bigtop.repo http://www.apache.org/dist/

This step is optional,

Running Hadoop
After installing Hadoop packages onto your Linux box, make sure that:
You have the latest JDK installed on your system as well. You can either get it from the official Oracle website (http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u29-download-513648.html
...
)
...
or
...
follow
...
the
...
advice
...
given
...
by
...
your
...
Linux
...
distribution
...
(e.g.
...
some
...
Debian
...
based
...
Linux
...
distributions
...
have
...
JDK
...
packaged
...
as
...
part
...
of
...
their
...
extended
...
set
...
of
...
packages).
...
If
...
your
...
JDK
...
is
...
installed
...
in
...
a
...
non-standard
...
location,
...
make
...
sure
...
to
...
add
...
the
...
line
...
below
...
to
...
the
...
/etc/default/hadoop
...
file
...
No Format
...
export JAVA_HOME=XXXX
...
Format the namenode
No Format sudo -u hdfs hadoop namenode -format
...
Start the necessary Hadoop services. E.g.
...
for
...
the
...
pseudo
...
distributed
...
Hadoop
...
installation
...
you
...
can
...
simply
...
do:
...
No Format
...
for i in hadoop-namenode hadoop-datanode hadoop-jobtracker hadoop-tasktracker ; do sudo service $i start ; done
...
Once your basic cluster is up and running it is a good idea to create a home directory on the HDFS:
No Format sudo -u hdfs hadoop fs -mkdir /user/$USER sudo -u hdfs hadoop fs -chown $USER /user/$USER
...
Enjoy your cluster
No Format hadoop fs -lsr / hadoop jar /usr/lib/hadoop/hadoop-examples.jar pi 10 1000
...
If you are using Amazon AWS it is important the IP address in /etc/hostname
...
matches
...
the
...
Private
...
IP
...
Address
...
in
...
the
...
AWS
...
Management
...
Console.
...
If
...
the
...
addresses
...
do
...
not
...
match
...
Map
...
Reduce
...
programs
...
will
...
not
...
complete.
No Format ubuntu@ip-10-224-113-68:~$ cat /etc/hostname ip-10-224-113-68
...
- If the IP address in /etc/hostname
...
- does
...
- not
...
- match
...
- then
...
- open
...
- the
...
- hostname
...
- file
...
- in
...
- a
...
- text
...
- editor,
...
- change
...
- and
...
- reboot

One

of

the

advantages

of

Bigtop

is

the

ease

of

installation
...
of

the

different
...
Hadoop
...
Components
...
without
...
having
...
to

hunt

for

a

specific

Hadoop

Component

distribution
...
and
...
matching

it

with

a

specific

Hadoop
...
version.
Please visit the link above to run some easy examples from the Bigtop distribution !
Provided at the link above are examples to run Hadoop 1.0.1 and nine other components from the Hadoop ecosystem (hive/hbase/zookeeper/pig/sqoop/oozie/mahout/whirr and flume).
