Affects Version/s: trunk
Fix Version/s: 4.3.0
Currently, Oozie has no way of setting hadoop.security.token.service.use_ip to the non-default value, as explained in
HADOOP-12954. Once that is resolved, we should have Oozie set hadoop.security.token.service.use_ip on startup via the new method added by HADOOP-12954.
hadoop.security.token.service.use_ip (default=true) is needed if your network is setup such that you need to use hostnames in delegation tokens instead of ip addresses.
- Ideally, hadoop.security.token.service.use_ip could be set on a per-cluster basis (because Oozie supports multiple clusters), however, like many of Hadoop's Security stuff, it's static so we can't. I think we should have Oozie use the Configuration associated with the default NN/JT/RM when setting this.
- We'll have to use reflection to do this because
HADOOP-12954will add a new method and we can't guarantee the method is there. If the method doesn't exist, there's no alternative to set hadoop.security.token.service.use_ip, so we'll just ignore it.
