Hi All, I am new to Hadoop. I have been reading and playing around with Hadoop, it seems like the namenode is a single point of failure. I read about the backup node which is basically a copy of the live namenode.
So if the namenode were to crash, what is some of the recovery model that people have in place. Is there a way to configure hadoop to flip the the backup node and use that as the primary name node if the primary namenode goes down.. Thanks in advance, John
