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

In the above defined schemas, the options/parameters like *k*, *m* etc. are subject to be
changed and they're to be interpreted by the corresponding codec.

> 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 to enforce EC.
