Dear MADlib community, We recently realized that upgrading to v1.13 fails due to a minor change in kNN help functions, that were not dropped in the upgrade scripts.
We have filed a JIRA: https://issues.apache.org/jira/browse/MADLIB-1197 and updated our Wiki pages for a workaround: https://cwiki.apache.org/confluence/display/MADLIB/Installation+Guide#InstallationGuide-01/11/18-UpgradingMADlibto1.13 Thanks, The MADlib team
