-------------------------------------------

             Summary: Configuration tries to read from an inputstream resource 
multiple times. 
                 Key: HADOOP-8573
                 URL: https://issues.apache.org/jira/browse/HADOOP-8573
             Project: Hadoop Common
          Issue Type: Bug
          Components: conf
    Affects Versions: 1.0.2, 0.23.3, 2.0.1-alpha, 3.0.0
            Reporter: Robert Joseph Evans
            Assignee: Robert Joseph Evans


If someone calls Configuration.addResource(InputStream) and then 
reloadConfiguration is called for any reason, Configruation will try to reread 
the contents of the InputStream, after it has already closed it.

This never showed up in 1.0 because the framework itself does not call 
addResource with an InputStream, and typically by the time user code starts 
running that might call this, all of the default and site resources have 
already been loaded.

In 0.23 mapreduce is now a client library, and mapred-site.xml and 
mapred-default.xml are loaded much later in the process.
