Sean Owen resolved SPARK-13701.
-------------------------------
Resolution: Not A Problem
Yeah, I don't think Spark works on arm64 because jblas does not. The thing I'm
not quite sure about is why it doesn't fail earlier and fall back to Java. On
both counts, it sounds like something considered not an issue for Spark.
However... jblas hasn't been used in Spark for a while. What version is this?
I'm closing this, but you can reply.
