Hi,

<property>
<name>fs.default.name</name>
<value>localhost:9000</value>
</property>
<!-- map/reduce properties -->
<property>
<name>mapred.job.tracker</name>
<value>localhost:9001</value>
</property>
For the fs.default.name and the mapred.job.tracker try to use the
hostname of your machine instead of localhost. When using
localhost:XXXX, hadoop servers are listen to the loopback interface. But
mapreduce jobs (I do not know exactly where) are seeing that the
connections to tasktrackers are issued using the 127.0.0.1 and are
trying to reverse dns the adress. Your system will not return localhost
but the real name of your machine. In most linux system, that name is
binded to an ethernet interface so jobs will try to connect to that
interface instead of the loopback one.
