Description

If the SystemML MLContext tests are run in a single JVM, errors such as "org.apache.spark.SparkException: Only one SparkContext may be running in this JVM" can be seen.

This error can be generated by:

mvn surefire:test -Dtest=FrameTest,MLContextTest,MLContextFrameTest,GNMFTest

These tests use both the new MLContext and old MLContext APIs.
