kou opened a new issue, #49456: URL: https://github.com/apache/arrow/issues/49456
### Describe the bug, including details regarding any error messages, version, and platform. #49415 / #49416 changed to use field names in FlatBuffers for map type but it's not correct change. Our specification defines "key"/"value"/"entries" for field names: https://github.com/apache/arrow/blob/8e625d0a34e6b668674b2e1be526752000d5c462/format/Schema.fbs#L127-L130 We can use other field names but using the standard field names are better. So we should revert #49416. ### Component(s) C++ -- This is an automated message from the Apache Git Service.
