Date Mon, 08 Oct 2012 21:44:02 GMT

     [ https://issues.apache.org/jira/browse/MAHOUT-1091?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Paritosh Ranjan updated MAHOUT-1091:
------------------------------------

    Attachment: MAHOUT-1091.patch

Just tried out of curiosity. The patch contains the fix and a junit test demonstrating the
fix. 

The math module's test cases pass after this fix. Have not checked the complete build yet.

> The iterator for the SequentialAccessSparseVector doesn't return any items beyond the
last non-zero.  This breaks some stuff pretty massively, but hopefully doesn't break much
user code since iterating through all elements of a sparse vector is a relatively rare thing
to do.
