• See https://github.com/opensearch-project/data-prepper/issues/2273#issuecomment-1464092972 .
• Starting from https://github.com/jaegertracing/jaeger/pull/4187, Jaeger HotROD no longer uses jaegertracing/jaeger-agent to receive jaegertracing/example-hotrod data, but directly uses otel/opentelemetry-collector-contrib. According to https://www.jaegertracing.io/docs/1.60/deployment/#agent , jaegertracing/jaeger-agent is considered a deprecated component. It does not make any sense.
• According to https://opentelemetry.io/docs/collector/installation/ and https://opentelemetry.io/docs/collector/deployment/agent/ , removing the use of the Jaeger Agent is very simple.

4921 does not actually remove the dependency on jaeger agent. Should I update my PR?
