How to query avro map column

Hi -- I've got dataset in avro format with one of the columns as 'map' data
type defined as:

{"name": "data", "type": {"type": "map", "values": "string"}

If the data column has say:

{"param1":"value1","param2":"value2"}

How do I go about writing a hive query to only extract 'param1' column?

Thanks!
