Description

parquet-mr (at least version 1.8.1-fast-201712141648170019-ab0622b)

writes to ColumnChunk's metadata dictionary_page_offset == 0 when it is (supposed?) equal to data_page_offset.

calculation of col_start in std::unique_ptr<PageReader> GetColumnPageReader(int i)

works incorrectly in this case.
