Edited mapred-site.xml,core-site.xml,hadoop-env.sh,hdfs-site.xml,masters and slaves.

I have 1 DataNode and 2 Namenodes.Both of them started successfully and I am able to see it in browser. Started start-mapred.sh and it started JobTracker and TaskTracker on the Namenode but unable to start Tasktracker on the datanaode.

Started Tasktracker and the following is the output.

->hadoop tasktracker

Though quite late to answer this, still does your mapred-site.xml contain mapred.job.tracker property ?

My job tracker runs on 8021, so the configuration is as follows:

<configuration>
<property>
<name>mapred.job.tracker</name>
<value>http://localhost:8021</value>
</property>
</configuration>

I faced such an issue due to missing properties.
