Sivaprasanna Sethuraman updated FLINK-16371:
--------------------------------------------
Description:
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.
