Subject Can't start datanode?
Date Fri, 27 May 2011 05:01:33 GMT
One of my datanodes got hung and I had to reboot and restart the
datanode & tasktracker. However the datanode fails to start with the
following error message.

Thanks in advance.



[root@hadoop20 init.d]# ./hadoop-0.20-datanode start
