Jaeger is not reloading the renewed certificates from filesystem even during connection setup

[sidharthabiswal]

We are using Jaeger for tracing purpose. The Jaeger collector makes connection with search engine to store the trace data in TLS mode. The certificates get renewed at a periodic interval. But the renewed certificates are not reloaded by Jaeger as in the collector log it shows the below line only.

Certificate has been removed, using the last known version ...

This line comes from https://github.com/jaegertracing/jaeger/blob/main/pkg/config/tlscfg/cert_watcher.go#L92

So Jaeger is able to recognize when the certificate gets renewed. But It is not reloading the new certificates as the below line is not printed in the Jaeger collector logs.

Loading modified certificate ...

https://github.com/jaegertracing/jaeger/blob/main/pkg/config/tlscfg/cert_watcher.go#L97

So, we would like to know the expected behaviour.
