In master node, the output of the "JPS" will contain a tasktracker, jobtracker, namenode, secondary namenode, datanode(optional, depending on your config) and your slaves will have tasktracker, datanodes in their jps output. If you need more help on configuring hadoop, i recommend you to take a look at http://www.michael-noll.com/tutorials/running-hadoop-on-ubuntu-linux-single-node-cluster/ > Here is the contents of the Hadoop node tree. The only thing that looks > like a log file are the dncp_block_verification.log.curr files, and those > are empty. > Note the presence of the in_use.lock files, which suggests that this node is > indeed being used. The logs will be in the "logs" directory in $HADOOP_HOME (hadoop home directory), are you looking for logs in this directory? -- Thanks, M.
