Re: In Compatible clusterIDs

Hi Nagarjuna,

Is it a test cluster? Do you have another cluster running close-by?
Also, is it your first try?

It seems there is some previous data in the dfs directory which is not
in sync with the last installation.

Maybe you can remove the content of
/Users/nagarjunak/Documents/hadoop-install/hadoop-2.0.3-alpha/tmp_20
if it's not usefull for you, reformat your node and restart it?

JM
