10.1. Mahout Validation

To validate mahout:

Create a test user:

hadoop fs -put /tmp/sample-test.txt /user/testuser

Create a mahout test output directory:

hadoop fs -mkdir /user/testuser/mahouttest

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 
```
