Setting up Mahout with Hadoop's fully-distributed mode

Once Apache Hadoop is successfully installed, we can integrate Apache Mahout with it using the following simple steps:

  1. Download and install Apache Mahout.

  2. Set the following environment variables:

    HADOOP_CONF_DIR="[HADOOP INSTALLATION DIRECTORY]/etc/hadoop"
HADOOP_HOME="[HADOOP INSTALLATION DIRECTORY]"
MAHOUT_HOME="[MAHOUT INSTALLATION DIRECTORY]"
