Make JSON SerDe First-Class SerDe

      Description

      According to the Hive SerDe Docs, there are some extra steps involved in getting the JSON SerDe to work:

      ROW FORMAT SERDE
      'org.apache.hive.hcatalog.data.JsonSerDe'
      STORED AS TEXTFILE

      In some distributions, a reference to hive-hcatalog-core.jar is required.
      ADD JAR /usr/lib/hive-hcatalog/lib/hive-hcatalog-core.jar;

      I would like to propose that we move this SerDe into first-class status:

      STORED AS JSONFILE

      The user should have to perform no additional steps to use this SerDe.
