Patrick Wendell created SPARK-8949:
--------------------------------------
Summary: Remove references to preferredNodeLocalityData in javadoc
and print warning when used
Key: SPARK-8949
URL: https://issues.apache.org/jira/browse/SPARK-8949
Project: Spark
Issue Type: Improvement
Components: Spark Core, YARN
Reporter: Patrick Wendell
Priority: Blocker
The SparkContext constructor that takes preferredNodeLocalityData has not
worked since before Spark 1.0. Also, the feature in SPARK-4352 is strictly
better than a correct implementation of that feature.
We should remove any documentation references to that feature and print a
warning when it is used saying it doesn't work.
