@Override
public void open(FileSystem fs, Path path) throws IOException {
super.open(fs, path);
if (keyClass == null) {
throw new IllegalStateException("Key Class has not been initialized.");
}
if (valueClass == null) {
throw new IllegalStateException("Value Class has not been initialized.");
}
CompressionCodec codec = null;
Configuration conf = fs.getConf();
if (!compressionCodecName.equals("None")) {
CompressionCodecFactory codecFactory = new CompressionCodecFactory(conf);
codec = codecFactory.getCodecByName(compressionCodecName);
if (codec == null) {
