[jira] [Created] (OOZIE-1637) Oozie client hangs when IPv6 is enabled

Robert Kanter created OOZIE-1637:
------------------------------------

             Summary: Oozie client hangs when IPv6 is enabled
                 Key: OOZIE-1637
                 URL: https://issues.apache.org/jira/browse/OOZIE-1637
             Project: Oozie
          Issue Type: Bug
          Components: client
    Affects Versions: trunk
            Reporter: Robert Kanter


When IPv6 is enabled, we saw the Oozie client hang on trying to connect to the Oozie server; there were no error messages or anything.  

The workaround was to do
{noformat}
export OOZIE_CLIENT_OPTS="-Djava.net.preferIPv4Stack=true"
{noformat}
to force Java to use IPv4.  

It would be nice if the client were to try IPv6, and if that fails, fallback to IPv4 instead of just hanging.
