Joseph K. Bradley commented on SPARK-6442: ------------------------------------------ [~mengxr] [~brkyvz] What was the motivation behind not using commons math? Actually, I was not clear on the scope of this JIRA: Was it to create thin wrappers around Breeze or to re-implement some of the operations which are less efficient in Breeze? [~srowen] Concerning Breeze, I think the reason we don't expose it is that it does not promise stable APIs and is not backed by a big contributor base. But I agree with the sentiment that we are spread very thin and should be careful about these nice-but-not-necessary features. At any rate, I'm pretty sure this is not slated for 1.5, so I'll remove that target label at least. > MLlib Local Linear Algebra Package > ---------------------------------- > > Key: SPARK-6442 > URL: https://issues.apache.org/jira/browse/SPARK-6442 > Project: Spark > Issue Type: New Feature > Components: MLlib > Reporter: Burak Yavuz > Priority: Critical > > MLlib's local linear algebra package doesn't have any support for any type of > matrix operations.
