Sorry file name should be mapred-site.xml. If it doesnt exist, You can
create one and add the property as defined in below.
Also in old version, Configuration can be defined in hadoop-site.xml, which
is deprecated in hadoop-0.20. If you have already configured in
hadoop-site.xml, Just make sure the following entry is in the right format
<HOST>:<PORT>
<configuration>
<property>
<name>mapred.job.tracker</name>
<value>HOST:PAIR</value>
</property>
</configuration>
