----------------------------------------
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.
