    Hi Guys…. Im new to hadoop and I am experimenting with Sandbox. I was able to insert data to HDFS, but in serialized format using the Avro source. How do I deserialize the data for further processing using pig/hive.

    Also any decent guide on the differences between the different sources like Thrift,Avro,NetCat and SysLog and their usage ?

    Thanks for the reply Yi … I will take a look at AvroSerde. But, is it not true that Hive is only for structured data ?. What about unstructured data that can be used thriugh Pig ?.

    Hi K S,

    Hive has AvroSerde to process avro data. Have you tried it?

    Thanks,
    Yi
