Can't we use getClasses from config instead? atleast this peice of code should be qualified
as util method.
{quote}
OK. I move it to {{Configuration}} and accept generic type as following:
{code}
public <U> List<Class<? extends U>> getClasses(String name, 
      Class<U> xface, List<Class<? extends U>> defaultValue) {
…
}
{code}

Why cann't it be HadoopIllegalArgumentException instead of IAException?
{quote}
{{HadoopIllegalArgumentException}} only accepts string, I’m not going to add an overload
constructor for it.

> If there is no native support or OpenSSL version is too low not supporting AES-CTR, but
{{OpensslAesCtrCryptoCodec}} is configured, we need to fall back it to JCE implementation.
