[jira] [Created] (PARQUET-2345) The Parquet Spec doesn't specify whether multiple columns are allowed to have the same name.

Jan Finis created PARQUET-2345:
----------------------------------

             Summary: The Parquet Spec doesn't specify whether multiple columns are allowed to have the same name.
                 Key: PARQUET-2345
                 URL: https://issues.apache.org/jira/browse/PARQUET-2345
             Project: Parquet
          Issue Type: Improvement
          Components: parquet-format
    Affects Versions: 1.13.1
            Reporter: Jan Finis


The parquet format specification doesn't say whether a Parquet file having columns with the same name (in the same struct, so really exactly the same name) is valid. I.e., say I have a Parquet file with two columns. Both are called x. Is this file a valid Parquet file?
