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

此脚本已弃用 . 而是使用start-dfs.sh和start-yarn.sh在[localhost]上启动namenodes

amtex @ localhost的密码：localhost：起始namenode，登录到/home/amtex/Documents/installed/hadoop/logs/hadoop-amtex-namenode-amtex-desktop.out

amtex@localhost's password:

localhost：启动datanode，登录到/home/amtex/Documents/installed/hadoop/logs/hadoop-amtex-datanode-amtex-desktop.out启动辅助名称节点[0.0.0.0]

amtex@0.0.0.0's password:

0.0.0.0：启动secondarynamenode，登录/home/amtex/Documents/installed/hadoop/logs/hadoop-amtex-secondarynamenode-amtex-desktop.out启动yarn守护程序启动resourcemanager，登录到/ home / amtex / Documents / installed /的hadoop /日志/纱线AMTEX-的ResourceManager-AMTEX-desktop.out

amtex@localhost's password:

localhost：启动nodemanager，登录到/home/amtex/Documents/installed/hadoop/logs/yarn-amtex-nodemanager-amtex-desktop.out

amtex@amtex-desktop:~$ jps

    您需要在机器之间设置密码少登录

    下面的链接有一步一步的步骤来设置ssh密码少登录

    希望这可以帮助！！！...

    根据我的研究，我按照这些步骤来避免上述问题

    step 1: ssh-keygen -t rsa -P ""

    step 2: cat $HOME/.ssh/id_rsa.pub >> $HOME/.ssh/authorized_keys

    现在我开始了hadoop

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

This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh
Starting namenodes on [localhost]
localhost: starting namenode, logging to /home/amtex/Documents/installed/hadoop/logs/hadoop-amtex-namenode-amtex-desktop.out
localhost: starting datanode, logging to /home/amtex/Documents/installed/hadoop/logs/hadoop-amtex-datanode-amtex-desktop.out
