Description

Using this exporter encounters a bug. I have tried dsn and k8s resolver; both cause bugs.

use dns resolver, config:

  loadbalancing/jaeger:
    routing_key: "traceID"
    protocol:
      otlp:
        # all options from the OTLP exporter are supported, except the endpoint
        timeout: 1s
        tls:
          insecure: true
        sending_queue:
          enabled: true
          storage: file_storage/all_settings
        retry_on_failure:
          enabled: true
          max_elapsed_time: 500s
    resolver:
      dns:
        hostname: jaeger-collector-headless.insight-system.svc.cluster.local
        port: "4317"
        interval: 1s
        timeout: 200ms

It's error logs:

I have noticed this:

opentelemetry-collector-contrib/exporter/loadbalancingexporter/loadbalancer.go

Line 236 in 21208c0

// something is really wrong... how come we couldn't find the exporter??

It also shows that something is wrong with the code.
