Hi Joep, I think you were looking at an outdated commit. There is no setHravenUserNamePut function anymore. There is only one set method which is for the queue name. And it does not return anything. Also, as you have suggested, I am already getting the username from HadoopConfUtil.getUserNameInConf . I think most of these are taken care of, except for having a HRAVEN_QUEUE_BYTES which I will add in.
