---------------------------------------
Summary: Misleading warning for SparkContext.getOrCreate "WARN
SparkContext: Use an existing SparkContext, some configuration may not take
effect."
Key: SPARK-16606
URL: https://issues.apache.org/jira/browse/SPARK-16606
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.1.0
Reporter: Jacek Laskowski
Priority: Minor
{{SparkContext.getOrCreate}} should really be checking whether the code gets
the already-created instance or creating a new one.
Just a nit-pick: the warning message should also be "Using..." not "Use"
