-------------------------------
Summary: Fix `native-image.propertie` in Scala Client
Key: SPARK-42449
URL: https://issues.apache.org/jira/browse/SPARK-42449
Project: Spark
Issue Type: Improvement
Components: Connect
Affects Versions: 3.4.0
Reporter: Zhen Li
The content of `native-image.propertie` file is not correct. This file may be
used by graal project to find the shaded contents.
e.g.
The content in `META-INF/native-image/io.netty` should also relocated, just as
in `grpc-netty-shaded`.
Now, the content of
`META-INF/native-image/io.netty/netty-codec-http2/native-image.properties` is
```
Args = --initialize-at-build-time=io.netty \
--initialize-at-run-time=io.netty.handler.codec.http2.Http2CodecUtil,io.netty.handler.codec.http2.Http2ClientUpgradeCodec,io.netty.handler.codec.http2.Http2ConnectionHandler,io.netty.handler.codec.http2.DefaultHttp2FrameWriter
```
but it should like
```
Args = --initialize-at-build-time=org.sparkproject.connect.client.io.netty \
--initialize-at-run-time=org.sparkproject.connect.client.io.netty.handler.codec.http2.Http2CodecUtil,org.sparkproject.connect.client.io.netty.handler.codec.http2.Http2ClientUpgradeCodec,org.sparkproject.connect.client.io.netty.handler.codec.http2.Http2ConnectionHandler,org.sparkproject.connect.client.io.netty.handler.codec.http2.DefaultHttp2FrameWriter
```
Other Transformer may need to be added
