[jira] [Commented] (MAHOUT-933) Implement mapreduce version of ClusterIterator

["Hudson (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MAHOUT-933?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13214175#comment-13214175 ] 

Hudson commented on MAHOUT-933:
-------------------------------

Integrated in Mahout-Quality #1362 (See [https://builds.apache.org/job/Mahout-Quality/1362/])
    MAHOUT-933: Refactored actual classification out of ClusterClassifier and into ClusteringPolicies. This
allows classifier to be completely generic as to the algorithm and gives policies correct use of e.g. fuzzyK 'm'
Introduced Canopy and MeanShift clustering policies for classification though not used by cluster iterator
Modified serialization of ClusterClassifiers to include ClusteringPolicy
Added ClusterClassifier serialization methods to exploded sequenceFile representation needed for MR
Updated Display examples and unit tests. All run (Revision 1292563)

     Result = FAILURE

> Right now, ClusterIterator consumes vectors only from in-memory and sequential hdfs. A mapreduce version to consume vectors needs to be implemented.
