start-dfs.sh command is not starting Hadoop JobTracker & TaskTracker

0 votes

Hi I am installing Hadoop on my laptop. When I run the script start-dfs. script gives following output

starting namenode, logging to /usr/lib/hadoop/bin/../logs/hadoop-namenode-ubuntu.out

localhost: starting datanode, logging to /usr/local/hadoop/bin/../logs/hadoop-datanode-ubuntu.out

localhost: starting secondarynamenode, logging to /usr/local/hadoop/bin/../logs/hadoop-secondarynamenode-ubuntu.out

Then when I execute jps, I get following:

18226 Jps
13291 NameNode
18394 DataNode
18449 SecondaryNameNode


I am not able to find JobTracker & TaskTracker. I am a newbie. Can anyone help me out?

start-dfs.sh script, only starts the HDFS daemons. For starting MapReduce services you can execute start-mapred.sh script.
