-----------------------------------
Update on this issue.
After some discussion with author of the fabric8 kubernetes-client[1], we have
get a conclusion that kubernetes-client could not work with jdk 8u252 because
of the okhttp bug. Currently, we could use "export HTTP2_DISABLE=true" to
disable the http2.
Once the fabric8 kubernetes new version(4.9.2, 4.10.2) released, we need to
bump the version and get a clean solution.

> Flink Azure CI doesn't hit this problem because it runs under jdk-8-8u242
>
> The reason is that the okhttp library which flink using doesn't work on
