Installation

Download the tarball (hadoop-2.4.1.tar.gz) from Hadoop website.

tar xzvf hadoop-2.4.1.tar.gz

Make sure JAVA_HOME is set to a Java installation. If it is not available, we can include it by editing etc/hadoop/hadoop-env.sh and specify the JAVA_HOME variable. For example

export JAVA_HOME=/usr/lib/jvm/java-6-openjdk-amd64

If everything works well, we can check that Hadoop runs by typing

hadoop version

Public datasets
