-------------------------------------
Summary: Streaming KMeans fails when executed in Sequential Mode
Key: MAHOUT-1380
URL: https://issues.apache.org/jira/browse/MAHOUT-1380
Project: Mahout
Issue Type: Bug
Components: Clustering
Affects Versions: 0.8
Reporter: Suneel Marthi
Assignee: Suneel Marthi
Fix For: 0.9
Streaming KMeans fails when executed in Sequential mode because it presently
doesn't ignore 'logsCRCFilter' (in sequential execution).
