I had this problem with vanilla Hadoop instalation and fixed the error by editting the hdfs-site.xml and updating the permissions to false.
This unfortunately has not fixed the Hortonworks problem.

outputStream = hdfs.create(new Path(“hdfs://”+HadoopLocation+”:54310/user/hadoop/raw/” + dateToday + “//” + timeStamp.getName()),
