[I] druid 35: protobuf desc loading fails (druid)
gl opened a new issue, #18730:
URL: https://github.com/apache/druid/issues/18730
### Affected Version
druid 35.0.0, dockerhub official containers
### Description
I'm running a druid cluster over managed k8s. A kafka+protobuf spec is working in 34 but failing in 35 (yes I know using 35 was maybe a bit early), due to the protobuf loading:
"protoBytesDecoder": {
"type": "file",
"descriptor": "http://processor-schema/flow.pb.desc",
"protoMessageType": "FlowMessage"
}
I tried moving to in-container files (using file:///), but it also fails or inline with base64 (gets a null pointer)
Cannot construct instance of org.apache.druid.data.input.protobuf.FileBasedProtobufBytesDecoder, problem: Descriptor not found in class path [file:///opt/druid/flow.pb.desc]
with inline:
Cannot construct instance of org.apache.druid.data.input.protobuf.InlineDescriptorProtobufBytesDecoder, problem: java.lang.NullPointerException
So there's something quite not right that looks like a regression.
No issues up to druid-34, I reverted and everthing worked appropriately.
I don't *need* druid 35 so no hurry for me but I thought you may want to know.

This should be fixed by #18770 and Druid 36+.
