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

En. Do we want use spark 1.6.1 as default?
Is any known issues for backwards compatibility?

> When building SystemML against newer Spark version (e.g., 1.6.1), two files failed to compile:
> src/main/java/org/apache/sysml/api/javaml/LogisticRegression.java
> src/main/java/org/apache/sysml/api/MLBlock.java
> Default version uses Spark 1.4.1 to maintain backwards compatibility and prevent utilizing interfaces only available in newer Spark versions.  It would be helpful to update (or provide additional) wrapper in cases where building against later Spark version is required.
