How to start hadoop without asking local machine password?

Question

amtex@amtex-desktop:~$ start-all.sh

This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh Starting namenodes on [localhost]

amtex@localhost's password: localhost: starting namenode, logging to /home/amtex/Documents/installed/hadoop/logs/hadoop-amtex-namenode-amtex-desktop.out

amtex@localhost's password:

localhost: starting datanode, logging to /home/amtex/Documents/installed/hadoop/logs/hadoop-amtex-datanode-amtex-desktop.out Starting secondary namenodes [0.0.0.0]

amtex@0.0.0.0's password:

0.0.0.0: starting secondarynamenode, logging to /home/amtex/Documents/installed/hadoop/logs/hadoop-amtex-secondarynamenode-amtex-desktop.out starting yarn daemons starting resourcemanager, logging to /home/amtex/Documents/installed/hadoop/logs/yarn-amtex-resourcemanager-amtex-desktop.out

amtex@localhost's password:

localhost: starting nodemanager, logging to /home/amtex/Documents/installed/hadoop/logs/yarn-amtex-nodemanager-amtex-desktop.out

amtex@amtex-desktop:~$ jps

Based on my research i follow these steps to avoid the above problem **stop1:** `ssh-keygen -t rsa -P ""` **stop2:** `cat $HOME/.ssh/id_rsa.pub >> $HOME/.ssh/authorized_keys` — KARTHIKEYAN.A, Oct 20 '16 at 06:22
