Description

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

export OOZIE_CLIENT_OPTS="-Djava.net.preferIPv4Stack=true"

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.
