Subject [jira] Created: (HADOOP-6220) Jetty wraps InterruptedExceptions by IOExceptions if interrupted in startup

Jetty wraps InterruptedExceptions by IOExceptions if interrupted in startup
---------------------------------------------------------------------------

                 Key: HADOOP-6220
                 URL: https://issues.apache.org/jira/browse/HADOOP-6220
             Project: Hadoop Common
          Issue Type: Bug
          Components: util
    Affects Versions: 0.21.0
            Reporter: Steve Loughran
            Priority: Minor


Following on some discusson on mapred-dev, we should keep an eye on the fact that Jetty uses
sleeps when starting up; jetty can be a big part of the delays of bringing up a node. When
interrupted, the exception is wrapped by an IOException, the root cause is still there, just
hidden.

If we want callers to distinguish InterruptedExceptions from IOEs, then this exception should
be extracted. Some helper method to start an http daemon could do this -catch the IOE, and
if there is a nested interrupted exception, rethrow it, otherwise rethrowing the original
IOE
