------------------------------------
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.
