[jira] [Created] (MAHOUT-999) KMeans failing to create correct
Clustering Policy
KMeans failing to create correct Clustering Policy
--------------------------------------------------
Key: MAHOUT-999
URL: https://issues.apache.org/jira/browse/MAHOUT-999
Project: Mahout
Issue Type: Bug
Reporter: Grant Ingersoll
Priority: Minor
Jenkins has been complaining about the cluster-reuters.sh example for a while and the issue appears to be due to trying to write a file to a directory that doesn't exist due to the fact that it is a file, not a directory.
{code}

[jira] [Resolved] (MAHOUT-999) KMeans failing to create correct
Clustering Policy
Posted by "Paritosh Ranjan (Resolved) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/MAHOUT-999?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Paritosh Ranjan resolved MAHOUT-999.
------------------------------------
Resolution: Fixed
Fix Version/s: 0.7
Fixed it for kmeans as will as fuzzykmeans. The current example clusters build is demonstrating that.
Now creating directories to write for Clustering Policies.

----------------------------------------
Will try to fix it soon. Running really short of time. Will do this first thing as soon as I get time.
Thanks for the debugging and Jira Issue.
