Andrew Or created SPARK-9580:
--------------------------------
Summary: Refactor TestSQLContext to make it non-singleton
Key: SPARK-9580
URL: https://issues.apache.org/jira/browse/SPARK-9580
Project: Spark
Issue Type: Bug
Components: SQL, Tests
Affects Versions: 1.4.0
Reporter: Andrew Or
Assignee: Andrew Or
Priority: Blocker
Because the TestSQLContext is a singleton object, there is literally no way to
start a SparkContext in the SQL tests since we disallow multiple SparkContexts
in the same JVM. Starting a custom SparkContext is useful when we want to run
Spark in "local-cluster" mode or enable the UI, which is normally disabled.
This is a blocker for 1.5 because we currently have tests entirely commented
out due to this limitation.
