I noticed that I was using the jdk 1.8, so I reinstalled the 1.7, but still I have an error at the start of the resource manager : service hadoop-yarn-resourcemanager start Job for hadoop-yarn-resourcemanager.service failed. See 'systemctl status hadoop-yarn-resourcemanager.service' and 'journalctl -xn' for details. And in the logfile I cannot see why it fails : 2015-11-19 17:52:34,827 INFO org.apache.hadoop.http.HttpServer2: Jetty bound to port 8088
2015-11-19 17:52:35,480 INFO org.apache.hadoop.service.AbstractService: Service ResourceManager failed in state STARTED; cause: org.apache.hadoop.yarn.webapp.WebAppException: Error starting http server
