------------------------------------------

             Summary: Find a better alternative to netlib-java
                 Key: SPARK-19744
                 URL: https://issues.apache.org/jira/browse/SPARK-19744
             Project: Spark
          Issue Type: New Feature
          Components: Build, ML, MLlib
    Affects Versions: 2.1.0
         Environment: Fedora 25 Linux on x86-64
            Reporter: Demi Marie Obenour


netlib-java is, by the author's own admission, [hard to build with native BLAS and LAPACK
support|https://github.com/fommil/netlib-java/issues/83#issuecomment-114014185].  For licensing
reasons, Spark cannot build with native BLAS and LAPACK support by default.  This means that
MLlib is very slow.

A better solution would be to fork netlib-java (and make it easier to build) or to create
an alternative that is easier to build.  Ideally, the native component should be as easy to
build as {{./configure && make && make install}}, and the Java component should
be a standard Maven build.
