----------------------------------
Summary: [C++] Correctly read DELTA_BYTE_ARRAY data written with
bug PARQUET-246
Key: ARROW-14089
URL: https://issues.apache.org/jira/browse/ARROW-14089
Project: Apache Arrow
Issue Type: Improvement
Reporter: Shan Huang
If a parquet file is written by parquet-mr before version 1.8.0, the bug
[PARQUET-246|https://issues.apache.org/jira/browse/PARQUET-246] will produce
data inconsistent with the encoding of DELTA_BYTE_ARRAY.
There are two solutions:
1. We should update the read side to recover data written with this bug.
2. We need to throw an exception if the parquet file is written by parquet-mr
before version 1.8.0 and has DELTA_BYTE_ARRAY encoding data.
