> {code}
> The problem is the constructor of {{Buckets}} with default visibility which is called from {{HadoopPathBasedBulkFormatBuilder}} . This works as long as both classes are loaded with the same classloader but when they are loaded in different classloaders, the access fails.
> {{Buckets}} is loaded with the system CL because it is part of flink-streaming-java.
>
> To solve this issue, we should change the visibility of the {{Buckets}} constructor to {{public}}.
