Subject dfs copyFromLocal/put fails
Date Wed, 18 Jun 2008 08:24:05 GMT
hi, 

i'm new in hadoop and im just testing it at the moment. 
i set up a cluster with 2 nodes and it seems like they are running
normally, 
the log files of the namenode and the datanodes dont show errors. 
Firewall should be set right. 
but when i try to upload a file to the dfs i get following message: 

hadoop@xyz:~/hadoop$ bin/hadoop dfs -put file.txt file.txt
