~ $ git clone git://github.com/ivankelly/hadoop-common.git
~ $ cd hadoop-common
~/hadoop-common $ mvn package -Pdist -DskipTests

Once compiled, you must configure the namenode.

~/hadoop-common $ export HADOOP_COMMON_HOME=$(pwd)/$(ls d hadoop-common-project/hadoop-common/target/hadoop-common*-SNAPSHOT)
~/hadoop-common $ export HADOOP_HDFS_HOME=$(pwd)/$(ls d hadoop-hdfs-project/hadoop-hdfs/target/hadoop-hdfs*-SNAPSHOT)
~/hadoop-common $ export PATH=$HADOOP_COMMON_HOME/bin:$HADOOP_HDFS_HOME/bin:$PATH

Edit $HADOOP_COMMON_HOME/etc/hadoop/hdfs-site.xml and add the following configuration.

<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
