This occurs when I don't pass the `hudi-flink-bundle` in the class path
explicitly. So I am not sure about the jdk incompatibility.
To summarize, if I pass the bundle explicitly in the class path
`(/opt/flink/lib/)` and update the pom as
```
<dependency>
<groupId>org.apache.hudi</groupId>
<artifactId>hudi-flink${flink.binary.version}-bundle</artifactId>
<version>${hudi.version}</version>
<scope>provided</scope>
</dependency>
```
, it throws
```
Caused by: java.util.concurrent.CompletionException:
java.lang.NoClassDefFoundError: Could not initialize class
org.apache.hudi.configuration.FlinkOptions at
java.base/java.util.concurrent.CompletableFuture.encodeThrowable(Unknown
Source) at
java.base/java.util.concurrent.CompletableFuture.completeThrowable(Unknown
Source) ... 2 more
```
And if I change the pom dependency for the bundle to be default and not
provided
```
<dependency>
<groupId>org.apache.hudi</groupId>
<artifactId>hudi-flink${flink.binary.version}-bundle</artifactId>
<version>${hudi.version}</version>
</dependency>
```
I get the following exception
```
java.util.concurrent.CompletionException: java.lang.NoSuchFieldError:
DATABASE_NAME\n\tat
java.base/java.util.concurrent.CompletableFuture.encodeThrowable(Unknown
Source)\n\tat
java.base/java.util.concurrent.CompletableFuture.completeThrowable(Unknown
Source)\n\t... 2 more\nCaused by: java.lang.NoSuchFieldError:
DATABASE_NAME\n\tat
org.apache.hudi.configuration.FlinkOptions.<clinit>(FlinkOptions.java:88)
```
Any pointers will be much appreciated @danny0405
