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

michele, can you resubmit the patch with the .patch extension? Don't worry about versioning, jira should recognise it as being later

> This was mentioned on HADOOP-3427, there is a property,  java.net.preferIPv4Stack, which you set to true for the java net process to switch to IPv4 everywhere. 
> As Hadoop doesn't work on IPv6, this should be set to true in the startup scripts. Hopefully this will ensure that Jetty will also pick it up.
