Make JSON SerDe First-Class SerDe

          Details

          • Type: New Feature
          • Status: Open
          • Priority: Major
          • Resolution: Unresolved
          • Affects Version/s: 3.0.0
          • Fix Version/s: None
          • Component/s: Serializers/Deserializers
          • Labels:
            None

            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.
