> The current EC codec supports a single coder only (by default pure Java
> implementation). If the native coder is specified but is unavailable, it
> should fallback to pure Java implementation.
> One possible solution is to follow the convention of existing Hadoop native
> codec, such as transport encryption (see {{CryptoCodec.java}}). It supports
> fallback by specifying two or multiple coders as the value of property, and
> loads coders in order.
