> 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.
