Root cause is in Jaeger Agent implementation. I filed a bug with Jaeger: jaegertracing/jaeger#1624

I will see if there is a good workaround.

tigrannajaryan · 2019-06-21T18:01:55Z

I submitted a PR to fix the bug in Jaeger: jaegertracing/jaeger#1625

There is no good workaround except adding a pause in our tests. I will do it if PR does not get merged quickly.

Add multiplexing/"pass through" mode where spans from sources other than the initiating node can be sent and they should be properly proxied to their final destination. If the currently received node is nil, use the previously received and non-nil node, and after processing spans, memoize the last received node. Updated the tests to lock-in this behavior. This change also adds in tests to ensure this behavior and to avoid regressions in the future. Fixes #43

tigrannajaryan · 2019-07-02T00:01:13Z

Jaeger PR is now fixed. However updating to use latest Jaeger is not straightforward. They have breaking changes.

Added a Sleep to work around a data race bug in Jaeger (jaegertracing/jaeger#1625) caused by stopping immediately after starting. Without this Sleep we were observing this bug on our side: open-telemetry#43 The Sleep ensures that Jaeger Start() is fully completed before we call Jaeger Stop(). TODO: Jaeger bug is already fixed, remove this once we update Jaeger to latest version. Testing done: make test
