> Key: MAHOUT-1658
> URL: https://issues.apache.org/jira/browse/MAHOUT-1658
> Project: Mahout
> Issue Type: Bug
> Components: Clustering
> Affects Versions: 0.9
> Environment: CentOS 6.6 with HDP 2.2
> Reporter: Ha Son Hai
> Assignee: Andrew Musselman
> Labels: hadoop
> Fix For: 0.11.0

> Original Estimate: 1h
> Remaining Estimate: 1h

> Hi,
> I was trying to run some examples of mahout on a hadoop platform and saw that
> when kmeans running in local host, it returned successfully. However, when it
> ran with HDFS, mahout looked for the intermediate results on localhost
> instead on HDFS if we use relative path.
> I have to use absolute path of the input and output if I want kmeans to run
> correctly.
> Here is an typical error when running on HDFS:
