Chapter 16. Installing Apache Mahout
Install Apache Mahout on the machine that will run it, either the Hadoop node or your client environment. Do not install it on every node in your cluster.
To install the Mahout RPM, use the following command:
RHEL/CentOS/Oracle Linux:
yum install mahout
For SLES:
zypper install mahout
For Ubuntu and Debian:
apt-get install mahout
To validate Mahout:
Create a test user:
hdfs dfs -put /tmp/sample-test.txt /user/testuserCreate a mahout test output directory:
hdfs dfs -mkdir /user/testuser/mahouttestSet up Mahout to convert the plain text file sample-test.txt into a sequence file that is in the output directory mahouttest:
mahout seqdirectory --input /user/testuser/sample-test.txt --output /user/ testuser/mahouttest --charset utf-8
