Make the --conf argument is before the 'namenode -format' argument. I
forgot to do this a couple times and it does not ready your config

i have tried this, e.g.
hadoop --config .... namenode -format
the command return:
06/11/09 22:34:55 INFO conf.Configuration: parsing
jar:file:/home/projects/bin/hadoop-0.8.0/hadoop-0.8.0.jar!/hadoop-default.xml
but according to the namenode log when running the start-all script
2006-11-09 22:35:27,608 ERROR org.apache.hadoop.dfs.NameNode:
java.io.IOException: NameNode not formatted:

any more hints? thanks...
