A common problem is that a boxA says to boxB my name is
boxA.localnetwork but boxB can not connect the box with the name
boxA.localnetwork since the name from the outside would be somthing
like:
boxA.companyDomain.com So double check that the name the boxA use to
identify itself against other boxes (host.conf) is also setuped in
the dns the other boxes use.

I've followed the steps in the media-style wiki for setting up a map
reduce system. I am only having one strange error when I attempt to
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
at. If "local", then jobs are run in-process as a single map
and reduce task.
</description>
</property>
</nutch-conf>
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
