Subject [jira] [Created] (HCATALOG-2) Support nested schema conversion between Hive an Pig
Date Wed, 06 Apr 2011 21:54:05 GMT
Support nested schema conversion between Hive an Pig
----------------------------------------------------

                 Key: HCATALOG-2
                 URL: https://issues.apache.org/jira/browse/HCATALOG-2
             Project: HCatalog
          Issue Type: Improvement
            Reporter: Julien Le Dem


Hive supports STRUCT and ARRAY
Pig supports Tuple and Bag
In both cases the types can be arbitrarily nested.
example:
STRUCT< foo : ARRAY<STRUCT < bar1: STRING, bar2: STRING > > mystruct
mytuple: ( foo: { t: ( bar1:chararray, bar2:chararray ) } )

HCatalog should support nested schema conversion.
