Tapan Halani commented on FLINK-21708:
--------------------------------------

[~rmetzger] I am a newbie to flink, and I am trying to deploy flink in my org on kubernetes, using a helm chart. I am seeing the same warning as above when submitting job via sql_client. As you described, I am adding the following config to my flink config file (source: [https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/config/#env-java-opts-all)] :

```
 env.java.opts.all: "--add-opens java.base/java.lang=ALL-UNNAMED" 
```

but this doesn't solve it. Can you please help with what I might be missing? Thank you
