-----------------------------------------------
Summary: HadoopCompressionBulkWriter fails with 'java.io.NotSerializableException'
Key: FLINK-16371
URL:
https://issues.apache.org/jira/browse/FLINK-16371 Project: Flink
Issue Type: Bug
Affects Versions: 1.10.0
Reporter: Sivaprasanna Sethuraman
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 created and ran it on a Hadoop cluster, and it has been working just fine. Will raise a PR in a day or so.
