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

             Summary: yarn web services should convert parse failures of appId to 400
                 Key: YARN-4746
                 URL: https://issues.apache.org/jira/browse/YARN-4746
             Project: Hadoop YARN
          Issue Type: Bug
          Components: webapp
    Affects Versions: 2.8.0
            Reporter: Steve Loughran
            Priority: Minor


I'm seeing somewhere in the WS API tests of mine an error with exception conversion of  a
bad app ID sent in as an argument to a GET. I know it's in ATS, but a scan of the core RM
web services implies a same problem


{{WebServices.parseApplicationId()}} uses {{ConverterUtils.toApplicationId}} to convert an
argument; this throws IllegalArgumentException, which is then handled somewhere by jetty as
a 500 error.

In fact, it's a bad argument, which should be handled by returning a 400. This can be done
by catching the raised argument and explicitly converting it
