Subject [jira] Created: (HADOOP-7118) NPE in Configuration.writeXml
Date Tue, 25 Jan 2011 22:51:46 GMT
NPE in Configuration.writeXml
-----------------------------

                 Key: HADOOP-7118
                 URL: https://issues.apache.org/jira/browse/HADOOP-7118
             Project: Hadoop Common
          Issue Type: Bug
    Affects Versions: 0.22.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Blocker
             Fix For: 0.22.0


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)
