Alejandro Abdelnur commented on OOZIE-689:
------------------------------------------

As done in the testcase of proxyuser for Hadoop MiniMRYarnCluster, we should 
inject all possible hosts

----
            StringBuilder sb = new StringBuilder();
            sb.append("127.0.0.1,localhost");
            for (InetAddress i : 
InetAddress.getAllByName(InetAddress.getLocalHost().getHostName())) {
                sb.append(",").append(i.getCanonicalHostName());
            }
            conf.set("hadoop.proxyuser." + oozieUser + ".hosts", sb.toString());

> Hadoop 1.x does not support the '*' wildcard and Hadoop 0.23.x does not 
> process the wildcard as such if the value is '*,hostlocal'. 
> Furthermore, in different OSes, depending on the network configuration, the 
> host name is resolved to IPs or names.
