[jira] [Commented] (SPARK-1675) Make clear whether computePrincipalComponents requires centered data

    [ https://issues.apache.org/jira/browse/SPARK-1675?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14039952#comment-14039952 ] 

Sandy Ryza commented on SPARK-1675:
-----------------------------------

I think it still wouldn't hurt to add a remark that input data doesn't need to be centered.  Should have marked this trivial when I filed it - not a big deal either way.
