> When using CompressWriterFactory with Hadoop compression codec, the execution
> fails with java.io.NotSerializableException.
> I guess this is probably to do with the the instance creation for Hadoop's
> CompressionCodec being done here at
> [CompressWriterFactory.java#L59|https://github.com/apache/flink/blob/master/flink-formats/flink-compress/src/main/java/org/apache/flink/formats/compress/CompressWriterFactory.java#L59]
> and thus it has to be sent over the wire causing the exception to be thrown.
> So I did a quick test on my end by changing the way the CompressionCodec is
> initialised and ran it on a Hadoop cluster, and it has been working just
> fine. Will raise a PR in a day or so.
