> Per [issue|https://github.com/FasterXML/woodstox/issues/157], woodstox-core
> 5.3.0 has security vulnerability and need to upgrade to 5.4.0 for fix.
> The Hadoop Configuration classes uses woodstox to parse the XML format
> (core-site.xml, ...) but
> * people don't normally put in DTDs
> * the XML format is not the wire format used when applications submit jobs to
> the yarn resource manager.
> * when parsing untrusted XML configuration files in restricted mode (eg.
> oozie workflows), DTD support is already disabled
