[jira] [Commented] (SPARK-16801) clearThreshold does not work for SparseVector

    [ https://issues.apache.org/jira/browse/SPARK-16801?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15399953#comment-15399953 ] 

Sean Owen commented on SPARK-16801:
-----------------------------------

{{clearThreshold}} is unrelated to vectors entirely. It's a threshold on the dot product. You'd have to provide a specific example, but I don't think this can be the actual problem if there is one.
