             Summary: Fix HTTP content type for ReconfigurationServlet
                 Key: HADOOP-11005
                 URL: https://issues.apache.org/jira/browse/HADOOP-11005
             Project: Hadoop Common
          Issue Type: Bug
          Components: conf
    Affects Versions: 2.5.0
            Reporter: Lei (Eddy) Xu
            Assignee: Lei (Eddy) Xu
            Priority: Minor


The reconfiguration framework introduced from HDFS-7001 supports reload 
configuration from HTTP servlet, using {{ReconfigurableServlet}}. 
{{ReconfigurableServlet}} processes a HTTP GET request to list the differences 
between old and new configurations in HTML, with a form that allows the user to 
submit to confirm the configuration changes. However since the response lacks 
HTTP "content-type", the browser renders the page as text file, which makes it 
impossible to submit the form.
