Spelling mistake? dfs.http.adress --> dfs.http.address

主题: fsck only working on namenode

Hi,

I've installed hadoop 1.0.3 on a cluster of about 25 nodes and till now,
it's working fine.
Recently, i had to use fsck in a map-process, which leads to a
connection refused error.
I read about this error, that i should check about firewalls and proper
configfiles etc.
The command is only working on the namenode.
If i use the browser for the command, it's working (although also
refused, but because of webusers permission)
I can use telnet to connect to the namenode.
In hdfs-site.conf, i set dfs.http.adress to hostname:50070. I tried
IP-adress and Hostname. I marked it as final.
I'm still getting this connecting refused error, when using fsck on a
node other then the namenode.

Any further suggesting would be great. The fsck command is used to check
the numbers of block, in which a file is stored on the hdfs. Maybe
there's another possibility?

Greetings

 wherever you are running fsck command,it's not getting dfs.http.address(Might be some other configurations are there in classpath where dfs.http.address not configured).

Please check classpath...
