>             Project: Flink
>          Issue Type: Bug
>          Components: Command Line Client
>    Affects Versions: 1.19.0
>            Reporter: Dmitriy Linevich
>            Priority: Minor
>
> If run flink kubernetes application with dynamic properties (including deprecated keys), it fails because of
> {code:java}
> java.lang.ClassCastException: class java.lang.String cannot be cast to class java.util.Map (java.lang.String and java.util.Map are in module java.base of loader 'bootstrap'){code}
> An error occurs because the value of an option key matches the connection of another option key
> Test Example inYamlParserUtilsTest:
> {code:java}
> @Test
> void testDumpNestedYamlFromFlatMapEqualSubkeyAndValue() {
>     Map<String, Object> flattenMap = new HashMap<>();
>     flattenMap.put("nested.key1.subKey1", "value1");
>     flattenMap.put("nested.key2.subKey1", "value2");
>     flattenMap.put("nested.key2", "subKey1");
>     flattenMap.put("nested.key3", "value3");
>     List<String> values = YamlParserUtils.convertAndDumpYamlFromFlatMap(flattenMap);
> } {code}
> In [ConfigurationUtils#convertConfigToWritableLines|https://github.com/apache/flink/blob/ea72d7f5ddf832329959ff78b5658748e2d689b0/flink-core/src/main/java/org/apache/flink/configuration/ConfigurationUtils.java#L247] exists flag _flattenYaml,_ I think we need to use it by cli option in client
