Not a host:port pair: local

[psdc1978]

Hi,

I defined in the mapred-site.xml the following property:
<configuration>
<property>
  <name>mapred.job.tracker</name>
  <value>local</value>
</property>
(...)
</configuration>

But when I start map reduce I get the error "Not a host:port pair: local".
How can I run MR with the local property?
