DataNode - IOException: Call failed on local exception

[bhavin pandya <bv...@gmail.com>]

Hi,

I am trying to configure nutch only on one server. So all modules i am
trying to run on localhost.
The tutorial i followed.
http://wiki.apache.org/nutch/NutchHadoopTutorial

I am using nutch-1.0-dev version and jdk 1.5.

When i run start-all.sh i found exception in datanode log file.
In secondary namenode log also i found same exception.
