Corey J. Nolet created SPARK-5260:
-------------------------------------
Summary: Expose JsonRDD.allKeysWithValueTypes() in a utility class
Key: SPARK-5260
URL: https://issues.apache.org/jira/browse/SPARK-5260
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Corey J. Nolet
Fix For: 1.3.0
I have found this method extremely useful when implementing my own method for
inferring a schema from parsed json. For now, I've actually copied the method
right out of the JsonRDD class into my own project but I think it would be
immensely useful to keep the code in Spark and expose it publicly somewhere
else- like an object called JsonSchema.
