datanode java.net.SocketException
hi. i'm trying to get hadoop running in the pseudo distributed
configuration and have checked out the latest code and used the instructions
located in the API:
http://lucene.apache.org/hadoop/docs/api/overview-summary.html
when i execute start-all.sh, the console output displays socket exceptions.
does anyone know what may be going on. seems like the data node is having
issues connecting to the namenode. i tried starting the namenode first
which works, and then starting the datanode but it can't seem to send a
heartbeat to the namenode in this single node configuration. i also tried
running the commands as root. the output is below:

thx marko. i'm using java 1.4.2_10 (fedora core v. 4 and linux v. 2.6.11).
i'll try using java 1.5 and see what happens.

i have the same problem. If i export
HADOOP_OPTS="-Djava.net.preferIPv4Stack=true"
then the datanodes works but my tasktrackers fails.
I have some boxes with java1.4 and boxes with java5. The boxes with
java5 works correct but the other boxes throws this SocketException.
What for a java version do you have installed?
