Thank you for your reply. I ran that command before and it works fine but hadoop fs -ls diplays the list of files in the user's directory but then hangs for quite a while (~ 10 minutes) before handing the command line prompt back, then if I rerun the same command there is no problem. That is why I would like to be able to leave safe mode automatically (at least I think it's related). Also, in the hdfs web page, clicking on the Live Nodes or Dead Nodes links hangs forever but I am able to browse the file system without any problem with the browser. There is no error in the logs. Please let me know what sort of details I can provide to help resolve this issue.
