Use java.net.preferIPv4Stack to force IPv4
------------------------------------------
Key: HADOOP-6056
URL: https://issues.apache.org/jira/browse/HADOOP-6056
Project: Hadoop Core
Issue Type: Improvement
Components: scripts
Affects Versions: 0.21.0
Reporter: Steve Loughran
Fix For: 0.21.0
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.
