yu peng created SPARK-21540:
-------------------------------

             Summary: add spark.sql.functions.map_keys and spark.sql.functions.map_values
                 Key: SPARK-21540
                 URL: https://issues.apache.org/jira/browse/SPARK-21540
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 2.2.0
            Reporter: yu peng


for dataframe/sql we support MapType, but unlike ArrayType, we can explode to unpack from it.
getItems is just not powerful enough for manipulate MapTypes

df.select(map_keys('$map')) and df.select(map_values('$map')) would be really useful
