Upgrade Apache Mahout. On the Mahout client machines, run the following command:
For RHEL/CentOS/Oracle Linux:
yum upgrade mahout
For SLES:
zypper remove mahout
zypper se -s mahout
You should see Mahout in the output.
Install Mahout:
zypper up mahout
For Ubuntu:
apt-get install mahout
Replace your configuration after upgrading. Copy /etc/mahout/conf from the template to the conf directory in mahout hosts.
To validate mahout:
Create a test user:
hadoop dfs -put /tmp/sample-test.txt /user/testuser
Set 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
