hi, I am new to hadoop. I have executed [had...@master hadoop]$ bin /start-dfs.sh starting namenode, logging to /hadoop/hadoop/bin/../logs /hadoop-hadoop-namenode-master.out master: starting datanode, logging to /hadoop/hadoop/bin/../logs /hadoop-hadoop-datanode-master.out slave1: starting datanode, logging to /hadoop/hadoop/bin/../logs /hadoop-hadoop-datanode-slave1.out slave2: starting datanode, logging to /hadoop/hadoop/bin/../logs /hadoop-hadoop-datanode-slave2.out master: starting secondarynamenode, logging to /hadoop/hadoop/bin/../logs /hadoop-hadoop-secondarynamenode-master.out
[had...@master hadoop]$ bin /start-mapred.sh starting jobtracker, logging to /hadoop/hadoop/bin/../logs /hadoop-hadoop-jobtracker-master.out master: starting tasktracker, logging to /hadoop/hadoop/bin/../logs /hadoop-hadoop-tasktracker-master.out slave2: starting tasktracker, logging to /hadoop/hadoop/bin/../logs /hadoop-hadoop-tasktracker-slave2.out slave1: starting tasktracker, logging to /hadoop/hadoop/bin/../logs /hadoop-hadoop-tasktracker-slave1.out I ve created a gutenberg folder and did all the commands before(when clustering a single node) cd /hadoop mkdir gutenberg cd gutenberg wget http://www.gutenberg.org/files/20417/20417.txt<http://www.linkedin.com/redirect?url=http%3A%2F%2Fwww%2Egutenberg%2Eorg%2Ffiles%2F20417%2F20417%2Etxt&urlhash=8ze3> wget http://www.gutenberg.org/dirs/etext04/7ldvc10.txt<http://www.linkedin.com/redirect?url=http%3A%2F%2Fwww%2Egutenberg%2Eorg%2Fdirs%2Fetext04%2F7ldvc10%2Etxt&urlhash=8iZ7> wget http://www.gutenberg.org/files/4300/4300.txt<http://www.linkedin.com/redirect?url=http%3A%2F%2Fwww%2Egutenberg%2Eorg%2Ffiles%2F4300%2F4300%2Etxt&urlhash=lSzx> cd /hadoop/hadoop bin/hadoop dfs -ls bin/hadoop dfs -copyFromLocal /hadoop/gutenberg gutenberg bin/hadoop dfs -ls gutenberg bin/hadoop dfs -rmr gutenberg-output Then when i run the following command bin/hadoop jar hadoop-0.20.2-examples.jar wordcount gutenberg gutenberg-output There is nothing displayed.. I ve configgured 2 slaves I ve given the IP address,hostnames in both... Why the gutenberg mapreduce can't functions.........
