spark git commit: SPARK-4900 [MLLIB] MLlib SingularValueDecomposition
ARPACK IllegalStateException
Repository: spark

refs/heads/master 31d435ecf -> 36c4e1d75
SPARK-4900 [MLLIB] MLlib SingularValueDecomposition ARPACK IllegalStateException
Fix ARPACK error code mapping, at least. It's not yet clear whether the error is what we expect from ARPACK. If it isn't, not sure if that's to be treated as an MLlib or Breeze issue.

Closes #4485 from srowen/SPARK-4900 and squashes the following commits:
