Xiangrui Meng updated SPARK-5814:
---------------------------------
Priority: Critical (was: Major)
> Remove JBLAS from runtime dependencies
> --------------------------------------
>
> Key: SPARK-5814
> URL: https://issues.apache.org/jira/browse/SPARK-5814
> Project: Spark
> Issue Type: Dependency upgrade
> Components: GraphX, MLlib
> Reporter: Xiangrui Meng
> Assignee: Xiangrui Meng
> Priority: Critical
>
> We are using mixed breeze/netlib-java and jblas code in MLlib. They take
> different approaches to utilize native libraries and we should keep only one
> of them. netlib-java has a clear separation between Java implementation and
> native JNI libraries, while JBLAS packs statically linked binaries that
> causes license issues (SPARK-5669). So we want to remove JBLAS from Spark
> runtime.
> One issue with this approach is that we have JBLAS' DoubleMatrix exposed (by
> mistake) in SVDPlusPlus of GraphX. We should deprecate it and replace
> `DoubleMatrix` by `Array[Double]`.
