Subject [jira] [Commented] (SPARK-4022) Replace colt dependency (LGPL) with commons-math
Date Tue, 21 Oct 2014 01:03:35 GMT

    [ https://issues.apache.org/jira/browse/SPARK-4022?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14177759#comment-14177759

Sean Owen commented on SPARK-4022:
----------------------------------

Yeah, looks like it is only in examples at least, so I don't know if Colt ever got technically
distributed (? I forget whether it goes out with transitive deps). But best to change it.
I can try it, since I know Commons Math well, unless someone's already on it.

> The colt library we use is LGPL-licensed:

> We need to swap this out for commons-math. It is also a very old library that hasn't
been updated since 2004.
