Hi Edson, I noticed that only the h01 nodes are running 2.6.32.9, the other broken DNs are 2.6.32.10.
Is there some reason you are running a kernel that is literally 2 weeks old? I wouldn't be at all surprised if there were a bug here, or some issue with your Debian "unstable" distribution... -Todd On Tue, Mar 30, 2010 at 3:54 PM, Edson Ramiro <erlfi...@gmail.com> wrote: > Hi all, > > Thanks for help Todd and Steve, > > I configured Hadoop (0.20.2) again and I'm getting the same error (Function > not implemented). > > Do you think it's a Hadoop bug? > > This is the situation: > > I've 28 nodes where just four are running the datanode. > > In all other nodes the tasktracker in running ok. > > The NN and JT are running ok. > > The configuration of the machines is the same, its a nfs shared home. > > In all machines the Java version is "1.6.0_17". > > This is the kernel version of the nodes, note that are two versions and in > both the > datanode doesn't work.
