How to import XML

  • #32908

    I would like to import an XML document into HCatalog, Based on the format I would expect multiple tables to be created. Is there a good way to import directly into HCatalog or should I break the file into something like multiple CSV’s and then import them to HCatalog?

    The HCatlog interfaces can support PIG and MR (Hive) for unstructured and structured data. Since its XML I recommend using the HCatlog and PIG interfaces called “load and store”. Here is more info about the interfaces:

    You may also structure the XML as a table and use the Hive interfaces (Hcatinputformat, Hcatoutoutformat). Hope this helps.




    Thank you for your recommendations! I’m a complete newbie so forgive my ignorance. Are you saying that I can use Pig to load and store the data into HCatalog and then once it’s in there I can use Hive to query it?


    Hi Member,
    Yes, you can use PIG to pretty much massage the data and once its in a structure hive can use, you can then query the data via hive sql.
