Opentelemetry java Automatic Instrumentation with zipkin exporter option is using OtlpGrpcSpanExporter

Question

I have a simple spring boot hello world application. Trying to send data to the Zipkin collector. But as per logs, it's trying to use OtlpGrpcSpanExporter. My application exposes a simple post rest API.

Following Opentelemetry docs https://opentelemetry.io/docs/java/getting_started/

java -javaagent:tools/opentelemetry-javaagent-all.jar \
-Dotel.exporter=zipkin \
-jar target/*.jar

[opentelemetry.auto.trace 2021-02-20 01:48:44:490 +0530] [grpc-default-executor-1] WARN io.opentelemetry.exporter.otlp.trace.OtlpGrpcSpanExporter - Failed to export spans. Error message: UNAVAILABLE: io exception [opentelemetry.auto.trace 2021-02-20 01:49:14:106 +0530] [grpc-default-executor-2] WARN io.opentelemetry.exporter.otlp.metrics.OtlpGrpcMetricExporter - Failed to export metrics io.grpc.StatusRuntimeException: UNAVAILABLE: io exception

Please let me know if I have to change anything.

I get the same problem and below command did the trick.

java -javaagent:tools/opentelemetry-javaagent-all.jar \
-Dotel.traces.exporter=zipkin \
-jar target/*.jar

I checked the source code. It looks the property name has been changed:

This is the command that really worked for me.

-Dotel.traces.exporter=zipkin -Dotel.metrics.exporter=none -Dotel.exporter.zipkin.endpoint=http://localhost:9411/api/v2/spans
