> Currently, GzipCodec only supports BuiltInGzipDecompressor, if native zlib is 
> not loaded. So, without Hadoop native codec installed, saving SequenceFile 
> using GzipCodec will throw exception like "SequenceFile doesn't work with 
> GzipCodec without native-hadoop code!"
> Same as other codecs which we migrated to using prepared packages (lz4, 
> snappy), it will be better if we support GzipCodec generally without Hadoop 
> native codec installed. Similar to BuiltInGzipDecompressor, we can use Java 
> Deflater to support BuiltInGzipCompressor.
