jaeger exporter configurations issue with version 0.103.1

[wmashal]

Hi

When I am configuring the opentelemetry in my k8s cluster using the "otel/opentelemetry-collector-contrib:0.103.1" in deployment mode with the following jaeger exporter configurations but I got errors (see below) when the collector trying to export the traces so as a workaround I am using zipkin to send my traces to Jaeger

The Original Configurations

apiVersion: v1
data:
  relay: |
    exporters:
      logging:
        loglevel: debug
      otlp/jaeger:
        endpoint: api-gw-center-jaeger-operator-jaeger-collector.monitoring-prometheus.svc.cluster.local:14250
        retry_on_failure:
          enabled: true
        sending_queue:
          enabled: true
        tls:
          insecure: true
      zipkin:
        endpoint: http://api-gw-center-jaeger-operator-jaeger-collector.monitoring-prometheus.svc.cluster.local:9411/api/v2/spans
    extensions:
      health_check:
        endpoint: ${env:MY_POD_IP}:13133
    processors:
      batch: {}
      memory_limiter:
        check_interval: 5s
        limit_percentage: 80
        spike_limit_percentage: 25
    receivers:
      opencensus:
        endpoint: 0.0.0.0:55678
      otlp:
        protocols:
          grpc:
            endpoint: 0.0.0.0:4317
          http:
            endpoint: 0.0.0.0:4318
    service:
      extensions:
      - health_check
      pipelines:

          - batch
          receivers:
          - otlp
        traces:
          exporters:
          - logging
          - otlp/jaeger

          - otlp
          - opencensus

The workaround in traces exporter I am using zipkin

@bogdandrutu can help ?

I find the issue I just drop the istio proxy from my Jaeger and changed the endpoint port in the configurations to 4317
