Please add @InterfaceAudience.Private to public class ECPolicyLoader

Sorry about this, I will fix it in next patch.

Please combine multiple Java exceptions in the same catch clause like,
{code:java}
} catch (ParserConfigurationException | IOException | SAXException e) {
throw new RuntimeException("Failed to load policy file: " + policyFile);
}
{code}

I agree and will follow the approach you suggested.

> 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.
