In reply to DINAKAR N K. Hi Dinakar, Simply edit the ~/.bashrc configuration file and copy the settings at end of file. echo "export HADOOP_HOME=/home/hadoop/hadoop export HADOOP_INSTALL=$HADOOP_HOME export HADOOP_MAPRED_HOME=$HADOOP_HOME export HADOOP_COMMON_HOME=$HADOOP_HOME export HADOOP_HDFS_HOME=$HADOOP_HOME export YARN_HOME=$HADOOP_HOME export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib/native export PATH=$PATH:$HADOOP_HOME/sbin:$HADOOP_HOME/bin" > ~/.bashrc

In reply to sidharth. It looks OpenSSH server is not running on your system. https://tecadmin.net/install-openssh-server-on-ubuntu-linuxmint/ Don't change the default port.
