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

             Summary: Webserver should not log errors when handling HTTP HEAD 
                 Key: IMPALA-11007
                 URL: https://issues.apache.org/jira/browse/IMPALA-11007
             Project: IMPALA
          Issue Type: Bug
            Reporter: Andrew Sherman
            Assignee: Andrew Sherman


If you send a HEAD request  to Impala's webserver, for  example
{code}
curl -I http://localhost:25000/metrics
{code}
then the logs will contain scary messages:
{code}
I1025 10:39:52.337021 3578299 webserver.cc:591] Webserver: error reading: Connection reset by peer
{code}
This does not happen with 
{code}
curl http://localhost:25000/metrics
{code}

Fix this by making the Impala webserver not send any content in replies to a HEAD message
