----------------------------------

             Summary: HCatalog should allow coversions for non-primitive map 
keys
                 Key: HCATALOG-474
                 URL: https://issues.apache.org/jira/browse/HCATALOG-474
             Project: HCatalog
          Issue Type: Bug
          Components: pig
    Affects Versions: 0.4
            Reporter: Feng Peng


HCatalog assumes map keys are primitive types. When the underlying data allows 
complex struct to be map keys, such as Thrift, HCatalog should provide an 
option to allow users to auto-convert the keys to strings. The default behavior 
is still rejecting the data, but the option to convert should be provided.
