Hi Michael, Thanks for your response. It doesn't seem to be an issue with safemode.
Even when I try the command dfsadmin -safemode get, the system hangs. I am unable to execute any FS shell commands other than hadoop fs -help. I am wondering whether this an issue with communication between the daemons? What should I be looking at there? Or could it be something else? When I do jps, I do see all the daemons listed. Any other thoughts. Thanks again and happy new year. -Jon On Dec 31, 2010, at 9:09 AM, Black, Michael (IS) wrote: > Try checking your dfs status > > hadoop dfsadmin -safemode get > > Probably says "ON" > > hadoop dfsadmin -safemode leave > > Somebody else can probably say how to make this happen every reboot.... > > Michael D.
