BohuTANG opened a new issue #241:
URL: https://github.com/apache/arrow-rs/issues/241
**Describe the bug**
In flight server/client mode, if the server schema is:
```
let schema = Schema::new(vec![
Field::new("name", DataType::Utf8, false),
Field::new("address", DataType::Utf8, false),
Field::new("priority", DataType::UInt8, false),
])
```
The client will get an error:
```
status: Internal, message: "missing field `metadata` at line 1 column 431",
details: [], metadata: MetadataMap { headers: {"content-type":
"application/grpc", "date": "Fri, 30 Apr 2021 08:43:12 GMT"} }
```
If we change the server schema(placehold an empty metadta) to:
```
let metadata: HashMap<String, String> = [("Key".to_string(),
"Value".to_string())].iter().cloned().collect();
let schema = Schema::new_with_metadata(vec![
Field::new("name", DataType::Utf8, false),
Field::new("address", DataType::Utf8, false),
Field::new("priority", DataType::UInt8, false),
], metadata)
```
All is ok.
I have removed this line from my local crate, it works too:
