> When the configuration is serialized it can emit warnings about deprecated properties
that the user did not specify.  Converting the config to XML causes all the properties in
the config to be processed for deprecation, and after HADOOP-8167 setting a proper config
property also causes the deprecated forms to be set.  Processing all the keys in the config
for deprecation therefore can trigger warnings for keys that were never specified by the user,
leaving users confused as to how their code could be triggering these warnings.
