Description
In HADOOP-7082 I stupidly introduced a regression whereby Configuration.writeXml will throw an NPE if it is called before any .get() call is made, since the properties member is not initialized. This is causing a failure in TestCapacitySchedulerWithJobTracker on my box, but doesn't appear to trigger any failures in the non-contrib tests since .get() is usually called first.
This JIRA is to fix the bug and add a unit test for writeXml in common (apparently it never had a unit test)
