Ah I see, that makes sense.
I've began refactoring the tests here:
https://github.com/joshfg/flink/blob/flink-4190/flink-streaming-connectors/flink-connector-filesystem/src/test/java/org/apache/flink/streaming/connectors/fs/bucketing/BucketingSinkTest.java
But have run into this strange exception in the
`testNonRollingSequenceFileWithoutCompressionWriter` test:
```
java.lang.IllegalStateException: Key Class has not been initialized.

```
Any ideas what would cause that? I've copied the HDFS cluster
initialisation exactly as it was in the original tests...
