Jaeger-operator: Flaky e2e-tests-examples2/simple-streaming test

The e2e test simple-streaming from the e2e-tests-examples2 suite is intermittently failing.

Running the tests for #914 locally, I was able to reproduce it and get the following information.

State of the cluster before the test timed out:

[jpkrohling]

@kevinearls is this something you could take a look?

[kevinearls]

@jpkrohling Yes, please assign it to me.

[sandangel]

We have the same issue when trying to connect to our existing Kafka cluster. Is there any update on the investigation?

[jpkrohling]

ping @kevinearls

[kevinearls]

@sandangel What are you seeing? I'm guessing it's something different from this and you need to open a new issue. If my memory is correct there was a time we were having intermittent test failures because either the Jaeger operator, Kafka (Strimzi) operator, or Kafka instance was taking too long to deploy. I don't think we've seen this in quite some time, but maybe @jpkrohling can confirm this.

[jpkrohling]

Indeed, it's been a while since I last saw an intermittent issue here. @sandangel, are you able to consistently reproduce this?

[sandangel]

I'm trying to configure the collector to connect to our existing kafka cluster. However, we consistently got the same error described above. cc @jpkrohling @kevinearls

@sandangel Ok, but that doesn't really have anything to do with the original issue here, which was tests failing because of timing issues. Can you either open a new issue here, or ask on the Jaeger email list or Slack? (See https://www.jaegertracing.io/get-in-touch/#via-chat-or-email)

@jpkrohling I think we can close this.

[sandangel]

Sure. I thought it is related because it has the same error msg. Anyway I can create another issue. thanks for your response ❤️❤️❤️
