Subject [jira] [Created] (HDFS-3330) If GetImageServlet throws an Error or RTE, response has HTTP "OK" status
Date Fri, 27 Apr 2012 00:01:14 GMT
Todd Lipcon created HDFS-3330:
---------------------------------

             Summary: If GetImageServlet throws an Error or RTE, response has HTTP "OK" status
                 Key: HDFS-3330
                 URL: https://issues.apache.org/jira/browse/HDFS-3330
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: name-node
    Affects Versions: 1.0.0, 2.0.0
            Reporter: Todd Lipcon
            Assignee: Todd Lipcon
            Priority: Critical


Currently in GetImageServlet, we catch Exception but not other Errors or RTEs. So, if the
code ends up throwing one of these exceptions, the "response.sendError()" code doesn't run,
but the finally clause does run. This results in the servlet returning HTTP 200 OK and an
empty response, which causes the client to think it got a successful image transfer.
