Subject Problem with Symlinks
Date Mon, 30 Jan 2012 21:27:56 GMT
Hi,

I am upgraded my cluster to hadoop 1.0.0, however, hdfs fails to start and I get the following
message:

###################################

starting namenode, logging to /home/local/trad/hadoop/cluster/hadoop-1.0.0.dfs/bin/../logs/hadoop-trad-namenode-master_dfs.out
slave001: /home/local/trad/hadoop/cluster/hadoop-1.0.0.dfs/bin/..: Aucun fichier ou dossier

Hadoop is installed as follows:

on master_dfs: /local/trad/hadoop/cluster/hadoop-1.0.0.dfs/ However the /local/ is actually
a symlink to /home/local so the actual path is : /home/local/trad/hadoop/cluster/hadoop-1.0.0.dfs/
on slave001,slave002,slave003: /local/trad/hadoop/cluster/hadoop-1.0.0.dfs/

How to force hadoop 1.0.0 to bypass this redirection?

Kind regards
