Review comment:
I think here it is more reasonable to throw an `IOException` and not an
`NPE` one. Also I would separate it into a different method like:
```
private void validateCompressionCodecConfig(String hadoopCodecName,
Configuration hadoopConfiguration) throws IOException {
CompressionCodec codec = new
CompressionCodecFactory(hadoopConfiguration).getCodecByName(hadoopCodecName);
if (codec == null) {
throw new IOException("Unable to load the provided
Hadoop codec [" + hadoopCodecName + "]");
}
}
```
What do you think @zenfenan ?
