Jaeger sampling problem

Hello there!

I am unable to increase the jaeger sampling %. I would like to increase it temporary but it is not working, it always stick at 1%.

Istio version: 1.10.0
Jaeger: latest

How did I install it all? Good question, and here ill list my steps:

  1. default istio install via istioctl

  2. installed jaeger with
    kubectl apply -f https://raw.githubusercontent.com/istio/istio/release-1.11/samples/addons/jaeger.yaml

  3. update istio to collect the data and increase sample with: istioctl install --set meshConfig.defaultConfig.tracing.zipkin.address=jaeger-collector.istio-system.svc.cluster.local:9411 --set meshConfig.defaultConfig.tracing.sampling=50

Did that and jaeger seems to work fine, but i am only getting 1%, not 50%.

Did I miss anything?
