[jira] [Created] (PARQUET-759) Cannot store columns consisting of empty strings

Uwe L. Korn created PARQUET-759:
-----------------------------------

             Summary: Cannot store columns consisting of empty strings
                 Key: PARQUET-759
                 URL: https://issues.apache.org/jira/browse/PARQUET-759
             Project: Parquet
          Issue Type: Bug
          Components: parquet-cpp
            Reporter: Uwe L. Korn
            Assignee: Uwe L. Korn


Currently we cannot store string columns that only consist of empty strings. In that case {{StringArray::data()}} points to a {{nullptr}} thus the call to {{StringArrays::data()::data()}} fails with a Segmentation fault in {{FileWriter::Impl::WriteFlatColumnChunk}}.
