this is also what I would expect. Nevertheless the last reboot caused the problem described at the beginning of the thread. During the tests today I always stopped the Datanode and Namenode by my own which works flawlessly. To be a little bit more safe I wrote my own stop-script which stops the datanode and the namenode before shutdown. best wishes, Björn
