Namenode, Jobtracker don't start correctly

[Vishal Shah <vi...@rediff.co.in>]

Hi All,
 
   I am trying to setup Nutch0.8 on a single machine with Hadoop for
testing. I followed the setup instructions in the NutchHadoop tutorial,
and the setup seemed to work initially after making a change in the
log4j.properties file. (I used to see an error from the logger saying
that "Either file or DatePattern options are not set". I just changed
the hadoop.log.file param to /my/nutch/dir/logs/hadoop.log - that fixed
the problem).
 
  However, after running a couple of small crawls, I seem to be having a
lot of rpc related problems. I am seeing the "rpc timed out" message
often when I try to start a crawl using the crawl tool. After running
turning the Debug logging, I saw the following exceptions in the log
file multiple times:

I compiled and am running Nutch/Hadoop using j2sdk1.4.2_05.
 
I'd appreciate any help I can get in getting the setup to work.
 
Thanks!
