I was just wondering why do we specify more than one directories for
What I understand is dfs.name.dir should be valued to 2 directories one on
the local and the other on the NFS.
Are we trying to protect the name node from eventualities? If so, what is
the role of Secondary NameNode ?
I am using apache hadoop-0.20
