Specifying the IP address gave the same error.
I did a grep -R through the XML configuration files and couldn't find
another place where anything was set to local.

Maybe try doing a "grep -R local<hadoop dir>" to see if its picking it up
from somewhere in there. Also, maybe try specifying an actual IP instead of
myserver as a test to see if name resolution is an issue.

All of the information I've seen online suggests that this is because
mapreduce.jobtracker.address is set to local. However, in
conf/mapred-site.xml I have
<property>
<name>mapreduce.jobtracker.address</name>
<value>myserver:8888</value>
<description>the jobtracker server</description>
</property>
which means that the jobtracker shouldn't be set to local in the first
place.
Does anyone have any pointers?
Thanks,
