Thanks for your comment Aljoscha,
So there are at least three ways on how to achieve it: either mark this
dependency as 'provided', move Hadoop Snappy Codec related classes to
flink-java module or move it to some separate module as suggested @haohui, but
I'm not sure what should be inside this module
> Flink should support reading Snappy Files

> Key: FLINK-5944
> URL: https://issues.apache.org/jira/browse/FLINK-5944
> Project: Flink
> Issue Type: New Feature
> Components: Batch Connectors and Input/Output Formats
> Reporter: Ilya Ganelin
> Assignee: Mikhail Lipkovich
> Labels: features
>
> Snappy is an extremely performant compression format that's widely used
> offering fast decompression/compression.
> This can be easily implemented by creating a SnappyInflaterInputStreamFactory
> and updating the initDefaultInflateInputStreamFactories in FileInputFormat.
> Flink already includes the Snappy dependency in the project.
> There is a minor gotcha in this. If we wish to use this with Hadoop, then we
> must provide two separate implementations since Hadoop uses a different
> version of the snappy format than Snappy Java (which is the xerial/snappy
> included in Flink).
