             Summary: Move minimum recommended Spark version to pom.xml
                 Key: SYSTEMML-1354
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-1354
             Project: SystemML
          Issue Type: Improvement
          Components: APIs, Build
            Reporter: Deron Eriksson
            Assignee: Deron Eriksson


Currently the minimum recommended Spark version in the MLContext is stored as a constant (public static final). Constants such as this typically are rather difficult to maintain since it's hard to tell which Java files need to be updated as the project matures. The minimum recommended Spark version can be moved to be a property in the pom.xml file, which is much easier to maintain since this configuration value is located in a single easily maintained location.

To do effectively, this should support both:
1) environment where SystemML jar file is being used. The minimum recommended Spark version can be placed in the jar file manifest and read using the ProjectInfo class.
2) development environment where SystemML jar file is not available but pom.xml file is available. XML parsing of the pom.xml can be used to obtain the minimum recommended Spark version.
