What happened

The class loads InternalConfigHolder as a cache class, and an object is regenerated when used (it should be the same one, otherwise the cache will become invalid, and everything will become the default value)

As follows:

1. Springboot startup
   

2. Springboot startup is completed, and the yaml configuration is refreshed into InternalConfigHolder through EnvInitializer
   

3. After springboot is started, click to start k8s sesssion deploy
   

It can be seen that after passing this classloader, InternalConfigHolder regenerates an object

Initially springboot service is initialized using java's original classloader

(sun/misc/Launcher$AppClassLoader)

When submitting the k8s flink task, Will use flink

(org/apache/streampark/flink/proxy/ChildFirstClassLoader)

This reinitializes InternalConfigHolder

[Xuxiaotuan]

I tried to add an output to InternalConfigHolder, printed it once after the initial service, and then submitted it to the flink environment. Will print again
