[jira] [Created] (SYSTEMML-915) MLContext tests in single JVM give SparkContext error

Deron Eriksson created SYSTEMML-915:
---------------------------------------

             Summary: MLContext tests in single JVM give SparkContext error
                 Key: SYSTEMML-915
                 URL: https://issues.apache.org/jira/browse/SYSTEMML-915
             Project: SystemML
          Issue Type: Bug
          Components: Test
            Reporter: Deron Eriksson
            Assignee: Deron Eriksson


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

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