| bad_rle_literal_count.parquet: |
| Generated by hacking Impala's Parquet writer. |
| Contains a single bigint column 'c' with the values 1, 3, 7 stored |
| in a single data chunk as dictionary plain. The RLE encoded dictionary |
| indexes are all literals (and not repeated), but the literal count |
| is incorrectly 0 in the file to test that such data corruption is |
| proprly handled. |

| bad_rle_repeat_count.parquet: |
| Generated by hacking Impala's Parquet writer. |
| Contains a single bigint column 'c' with the value 7 repeated 7 times |
| stored in a single data chunk as dictionary plain. The RLE encoded dictionary |
| indexes are a single repeated run (and not literals), but the repeat count |
| is incorrectly 0 in the file to test that such data corruption is proprly |
| handled. |

| there are 11 values (instead of 10). The third rowgroup has the correct metadata. |
