> According to recent discussions with [~andrew.wang] in HDFS-7337, it would be
> good to support allowing users to define their own erasure code codecs,
> schemas and policies via an XML file. The XML file can be passed to a CLI cmd
> to parse and send to NameNode to persist and maintain.
> Open this task to define the XML format providing a default sample file to
> put in the configuration folder for users' reference, and implement the
> necessary parser utility.
