I get the same error sometimes, although everything seems to work fine
after that, even though it gives that error, so it's probably not a problem.

I've followed the steps in the media-style wiki for setting up a map

start the tasktrackers. Here is my output:

I have configured my nutch-site.xml as follows on each box:
?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="nutch-conf.xsl"?>
<!-- Put site-specific property overrides in this file. -->
<nutch-conf>
<property>
<name>fs.default.name</name>
<value>srv05.xxxxx.com:50000</value>
<description>The name of the default file system. Either the
literal string "local" or a host:port for NDFS.</description>
</property>
<property>
<name>mapred.job.tracker</name>
<value>srv05.xxxxx.com:50020</value>
<description>The host and port that the MapReduce job tracker runs

srv05 is my namenode and jobtracker. That server starts up the namenode
and jobtracker services just fine. Maybe I am supposed to reference
fs.default.name as srv08:50000 on srv08? I thought from reading the
mediawiki that I need to reference my BoxA on every other machine.
No firewall on this internal network so I am wondering why I am getting
a connection refused. Anyone have any ideas?
Thanks,
Mike
