What's the best way to check the compression codec that an HDFS file was written with?
We use both Gzip and Snappy compression so I want a way to determine how a specific file is compressed. The closest I found is the *getCodec <http://hadoop.apache.org/docs/current/api/org/apache/hadoop/io/compress/CompressionCodecFactory.html#getCodec(org.apache.hadoop.fs.Path)> *but that relies on the file name suffix ... which don't exist since Reducers typically don't add a suffix to the filenames they create. Thanks
