The way it works in pre 0.16 is that you start the cluster, and
issue:
hadoop dfsadmin -finalizeUpgrade
I've just run that again. Now the 'previous' dir on the namenode
is gone. But on the data nodes the 'previous' is still there.
That means finalizeUpgrade has not been run before or failed for
some reason.
Now, if you still want to do it manually, then yes just remove
"previous"
dir on the name-node and then start the cluster.
Data-nodes will finalize automatically.
Hmmm ...I cannot see that happening. Now what?
Finalizing on the data-nodes is very lazy.
During registrations and block reports the name-node will inform
data-nodes
whether it has the previous state or not. If not the data-nodes
will remove
their previous states.
On the running cluster a complete previous state removal can take
up to one hour.
If you need to accelerate it - restart the cluster.
But it should be done by now. There's been 3 hours since you wrote
this.
Yepp ...you were right :) 'previous' is gone now.
cheers
