> System administrator can configure multiple EC codecs in hdfs-site.xml file,
> and codec instances or schemas in a new configuration file named
> ec-schema.xml in the conf folder. A codec can be referenced by its instance
> or schema using the codec name, and a schema can be utilized and specified by
> the schema name for a folder or EC ZONE to enforce EC. Once a schema is used
> to define an EC ZONE, then its associated parameter values will be stored as
> xattributes and respected thereafter.
