Sean Owen commented on SPARK-4816:
----------------------------------

I tried your exact build above and I get lots of hits for netlib-native:

{code}
$ zipinfo -1 assembly/target/scala-2.10/spark-assembly-1.4.1-hadoop2.4.0.jar | grep netlib-native
netlib-native_ref-osx-x86_64.jnilib
netlib-native_ref-osx-x86_64.jnilib.asc
netlib-native_ref-osx-x86_64.pom
netlib-native_ref-osx-x86_64.pom.asc
META-INF/maven/com.github.fommil.netlib/netlib-native_ref-osx-x86_64/
META-INF/maven/com.github.fommil.netlib/netlib-native_ref-osx-x86_64/pom.xml
META-INF/maven/com.github.fommil.netlib/netlib-native_ref-osx-x86_64/pom.properties

META-INF/maven/com.github.fommil.netlib/netlib-native_ref-linux-x86_64/pom.xml
META-INF/maven/com.github.fommil.netlib/netlib-native_ref-linux-x86_64/pom.properties
netlib-native_ref-linux-i686.so
...
{code}

Still not sure what to make of the difference here, though it seems to work here. You're saying
that at worst you think it's fixed for 1.4.2 by SPARK-9507. In that case I suppose it's already
resolved, just not in the 1.4.1 release. But as I say it does seem to work for me.

> When doing what the documentation recommends to recompile Spark with Netlib Native system
binding (i.e. to bind with openblas or, in my case, MKL), 
> mvn -Pnetlib-lgpl -Pyarn -Phadoop-2.3 -Dhadoop.version=2.3.0 -DskipTests clean package
> The resulting assembly jar still lacked the netlib-system class. (I checked the content
of spark-assembly...jar)
> When forcing the netlib-lgpl profile in MLLib package to be active, the jar is correctly
built.
> So I guess it's a problem with the way maven passes profiles activitations to children
modules.
> Also, despite the documentation claiming that if the job's jar contains netlib with necessary
bindings, it should works, it does not. The classloader must be unhappy with two occurrences
of netlib ?
