Hi, The error you are getting is due to your port is not free please check it as Harsh told. Another problem is with your configuration file if you setup hadoop cluster then there should not be localhost. you files should look like:
core-site.xml <property> <name>fs.default.name</name> <value>hdfs://master:54310</value> </property> mapred-site.xml <property> <name>mapred.job.tracker</name> <value>master:54311</value> </property> hdfs-site.xml <property> <name>dfs.replication</name> <value>2</value> </property> you can visit http://hadoop-tutorial.blogspot.com/2010/11/running-hadoop-in-distributed-mode.html -- *Regards*, Rahul Patodi Software Engineer, Impetus Infotech (India) Pvt Ltd, www.impetus.com Mob:09907074413
