    Description

      As of Spark 2.0, Spark falls back to Hive for only the following built-in functions:

          "elt", "hash", "java_method", "histogram_numeric",
          "map_keys", "map_values",
          "parse_url", "percentile", "percentile_approx", "reflect", "sentences", "stack", "str_to_map",
          "xpath", "xpath_boolean", "xpath_double", "xpath_float", "xpath_int", "xpath_long",
          "xpath_number", "xpath_short", "xpath_string",
      
          // table generating function
          "inline", "posexplode"
      

      The goal of the ticket is to implement all of these in Spark so we don't need to fall back into Hive's UDFs.
