Hotrod - failed to flush Jaeger spans

[QAInsights]

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)

I wonder if the URL http://docker.for.mac.localhost:14268/api/traces is right, did you tried sending the data into an inspectable HTTP server e.g. using httpmole?
