--------------------------------
Summary: Spark assembly includes incompatibly licensed
libgfortran, libgcc code via JBLAS
Key: SPARK-5669
URL: https://issues.apache.org/jira/browse/SPARK-5669
Project: Spark
Issue Type: Bug
Components: Build
Reporter: Sean Owen
Priority: Blocker
Fix For: 1.3.0
Sorry for "Blocker", but it's a license issue. The Spark assembly includes the
following, from JBLAS:

{code}
Unfortunately the libgfortran and libgcc libraries included for Windows are not
licensed in a way that's compatible with Spark and the AL2 -- LGPL at least.
It's easy to exclude them. I'm not clear what it does to running on Windows; I
assume it can still work but the libs would have to be made available locally
and put on the shared library path manually. I don't think there's a package
manager as in Linux that would make it easily available. I'm not able to test
on Windows.
If it doesn't work, the follow-up question is whether that means JBLAS has to
be removed on the double, or treated as a known issue for 1.3.0.
