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

             Summary: [C++] parquet::arrow::FileReader::GetRecordBatchReader has logical error on row groups with chunked columns
                 Key: ARROW-3822
                 URL: https://issues.apache.org/jira/browse/ARROW-3822
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Wes McKinney
             Fix For: 0.13.0


If a BinaryArray / StringArray overflows a single column when reading a row group, the resulting table will have a ChunkedArray. Using TableBatchReader in 

https://github.com/apache/arrow/blob/master/cpp/src/parquet/arrow/reader.cc#L176

will therefore only return a part of the row group, discarding the rest
