Hotrod - failed to flush Jaeger spans

[QAInsights]

I raised this issue in here, but couldn't get any updates. Hence, posting it in here.

Use Case

I am trying to trace the hot rod requests in Hypertrace. But I am getting "failing to flush errors".

• Started Hypertrace
• Able to access Hypertrace UI at 2020
• Started Hotrod
• Able to access Hotrod application at 8080
• But the trace is not getting displayed in the Hypertrace UI. In Hotrod, I am seeing
  " failed to flush Jaeger spans to server: Post "http://docker.for.mac.localhost:14268/api/traces": dial tcp 127.0.0.1:14268: connect: connection refused {"service": "driver"}" error.

Same case with TODO app as well.

Proposal

NA

Questions to address (if any)

Hey @QAInsights !

Thanks for opening the issue.

Can you please try running the hotrod app with following command?

docker run \
  --rm \
  --env JAEGER_ENDPOINT=http://host.docker.internal:14268/api/traces \
  -p8080:8080 \
  jaegertracing/example-hotrod:latest \
  all

And try sending traces?

I tried to reproduce this but it's not happening for me somehow.
