When executing commands in Hadoop, the framework may need to interact with other nodes in the cluster using SSH. The error message “SSH exited with exit code 255” indicates that there was an issue with the SSH connection between the nodes. The exit code 255 generally signifies an authenticat...

sudo apt-get install openssh-server ssh localhost 首次使用ssh时,会提示是否继续链接,输入yes,然后输入密码hadoop,就登录到本机了,目前每次都要输入密码 为了免密码登录,需要用ssh-keygen生成秘钥,并将其加入到授权中: exit 先退出刚刚登陆的localhost cd ~/.ssh/ 在第一次执行ssh会生成该目录 ssh-keygen -t...

1. 下载Hadoop源码 直接到官方下载源码包,解压到需要的目录下面就行 我是在c盘下建立了一个hadoop目录,然后把源代码解压进去了。需要注意的是,最后那个hadoop-yarn-project的子目录很深,所以要尽可能把代码解压到靠近根目录的位置。否则,在我正版的win11家庭版上,会因为目录长度限制而无法解压(其实似乎无论如何都...
1. 对于CenterOS7系统,内置Docker,可以直接安装 [root@hadoop111 ~]# yum install -y docker 复制代码 2. 启动Docker [root@hadoop111 ~]# service docker startRedirecting to /bin/systemctl start docker.serviceJob for docker.service failed because the control process exited with error code. See "syst...
问题解决了,追踪溯源了一下,发现该节点经常出现问题pdsh@blockchain-004: blockchain-003: ssh exited with exit code 1。 推测:节点与master的ssh连接断开了,但节点本地的NodeMagager进程当时仍在运行;此时Master重连上该点的SSH之后,尝试重启该节点的NodeMagager服务,造成服务冲突出错。而当我发现时,之前的NodeMan...
1.创建centos-ssh-root 1.1 创建 centos-ssh-root dockerfile 注意: 这里面 我们先安装 了 vim,本人喜欢vim,不喜欢vi 先安装which ,后面 hadoop format 需要用到 # 选择一个已有的os镜像作为基a础 FROM docker.io/centos # 镜像的作者 MAINTAINER baoyou curiousby # 安装openssh-server和sudo软件包,并且将...
问题1: 报错信息如下: Container exited with a non-zero exit code 143 Killed by external signal 解决方案: 分配的资源不够,加大内存或者调整代码,尽量避免类似JsonObject这样的大对象过度消耗内存,或者Include below properties in yarn-site.xml and restart VM <property> <name>yarn.nodemanager.vmem-check-...
