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

             Summary: native openblas library doesn't work: undefined symbol: cblas_dscal
                 Key: SPARK-5010
                 URL: https://issues.apache.org/jira/browse/SPARK-5010
             Project: Spark
          Issue Type: Bug
          Components: MLlib
    Affects Versions: 1.3.0
         Environment: standalone
            Reporter: Tomas Hudik
            Priority: Minor


1. compiled and installed open blas library
2, ln -s libopenblas_sandybridgep-r0.2.13.so /usr/lib/libblas.so.3
3. compiled and built spark:
mvn -Pnetlib-lgpl -DskipTests clean compile package
4. run: bin/run-example  mllib.LinearRegression data/mllib/sample_libsvm_data.txt

I followed guide: https://spark.apache.org/docs/latest/mllib-guide.html section dependencies.

Am I missing something?
How to force Spark to use openblas library?

Thanks, Tomas
