Balancing export to jaeger in openTelemetry collector

Question

I have configuration as documentation says

exporters:
  jaeger:
    endpoint: "ipv4:firstHost:14250,secondHost:14250"
    balancer_name: "round_robin"

Collector produces error. How I can configure collector to balance exporter for sending requests in different backends?

info exporterhelper/queued_retry.go:276 Exporting failed. Will retry the request after interval. {"component_kind": "exporter", "component_type": "jaeger", "component_name": "jaeger", "error": "failed to push trace data via Jaeger exporter: rpc error: code = Unavailable desc = last connection error: connection error: desc = "transport: Error while dialing dial tcp: address ipv4:firstHost:14250,secondHost:14250: too many colons in address"", "interval": "30.456378855s"}

Answer 1

It doesn't work in golang grpc client. I used openTelemetry load balancing Another option - use kubernetes to balance requests to backends.
