Sorry, it looks like the UI and report feature will appear only in
0.16.
It is related to HADOOP-1604.
In general you are not supposed to remove any directories manually.
That's why I am so careful :)
You should just use finalizeUpgrade.
Well, from the output it looks like that has been run. At least I
cannot see any sign telling me I still need to run it ...still was
the previous directory on the name node.
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.
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?
cheers
