Subject [jira] [Created] (MAPREDUCE-3128) WebAppContext should also be stopped and cleared
Date Fri, 30 Sep 2011 10:51:45 GMT
WebAppContext should also be stopped and cleared
------------------------------------------------

                 Key: MAPREDUCE-3128
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-3128
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.24.0
            Reporter: Devaraj K
            Assignee: Devaraj K


1. If listener stop method throws any exception then the webserver stop method will not be
called

{code}
public void stop() throws Exception {
    listener.close();
    webServer.stop();
}
{code}

2. also, WebAppContext stores all the context attributes, which does not get cleared if only
webServer is stopped.
so following calls are necessary to ensure clean and complete stop.
{code}
webAppContext.clearAttributes();
webAppContext.stop();
{code}

3. Also the WebAppContext display name can be the name passed to HttpServer instance.
{code}
webAppContext.setDisplayName(name);
{code}

instead of

{code}
webAppContext.setDisplayName("WepAppsContext");
{code}
