------------------------------------

Hi Kai,

Looks like you misunderstood what I meant. I meant to introduce a new class say {{ErasureCodecOptions}}.
Could we avoid changing into HDFS side, since HDFS is still using the raw coder APIs.

And also, would you help clean the following block in {{CommonConfigurationKeys}}? It's bad
to mess the common place (not caused by this). Maybe the default values could be defined in
{{CoderUtil}} place.
{code}
import org.apache.hadoop.io.erasurecode.codec.HHXORErasureCodecFactory;
import org.apache.hadoop.io.erasurecode.codec.RSErasureCodecFactory;
import org.apache.hadoop.io.erasurecode.codec.XORErasureCodecFactory;
import org.apache.hadoop.io.erasurecode.rawcoder.RSRawErasureCoderFactory;
import org.apache.hadoop.io.erasurecode.rawcoder.RSRawErasureCoderFactoryLegacy;
import org.apache.hadoop.io.erasurecode.rawcoder.XORRawErasureCoderFactory;
{code}
