strange problem with ndfs

Stefan Groschupf-2
Hi,

with the latest mr branch I have a strange problem copy a file from  
local to the ndfs.
Has anyone manage to use the ndfs client with this branch until last  
days?
The problems occurs until connecting to a datanode to get the next  
free block:

cluster2:~/mr_nutch-0.8-dev myuser$ bin/nutch ndfs -copyFromLocal  
nutch-0.8-dev.jar /tester
