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

             Summary: Clarify parquet-format specification for LIST and MAP structures.
                 Key: PARQUET-113
                 URL: https://issues.apache.org/jira/browse/PARQUET-113
             Project: Parquet
          Issue Type: Bug
          Components: parquet-format, parquet-mr
            Reporter: Ryan Blue
            Assignee: Ryan Blue


There are incompatibilities in the way that some parquet object models translate nested structures annotated by LIST and MAP / MAP_KEY_VALUE. We need to define clearly what the structures should look like and how to interpret existing structures, including what must be supported to read current parquet-avro, parquet-thrift, etc. files.
