jobtracker.info could only be replicated to 0 nodes, instead of 1
Hi,
I think its a well known and old problem. but I the reformatting trick
failed to work for me.
I can start the namenode and datanode properly.
hadoop dfsadmin -report

but when I try to start the jobtracker, I get the following error:

solved.
I have a virtual machine with 2GB of memory. So, I can not put block size
of 4GB.
