namenode和jobtracker不以start-all.sh开头 [英] namenode and jobtracker dont start with start-all.sh

问题描述

我正在尝试安装hadoop单节点。



当我执行start-all.sh时，名称节点和作业跟踪器无法启动。



你在我的档案中看到了什么可能是错的所以我有这个结果吗？



hadoop jps comman的结果 d：

Im trying to install hadoop single node.

When I do start-all.sh name node and job tracker dont start.

Do you see in my files what can be be wrong so Im having this result?

Result of hadoop jps command:

14878 Jps

14823 TaskTracker

14605 SecondaryNameNode

14456 DataNode

start-all.sh命令的结果： < br $> b $ b

Result of start-all.sh command:

推荐答案

start-all.sh
起始名字节点，登录到/usr/local/hadoop/libexec/../logs/hadoop-admin-namenode-vm-10.vd.uk.pt.out
localhost：启动datanode，登录到/ usr / local / hadoop / libexec /../ logs / hadoop-admin-datanode-vm-10.vd.uk.pt.out
localhost：启动secondarynamenode，登录到/usr/local/hadoop/libexec/../logs /hadoop-admin-secondarynamenode-vm-10.vd.uk.pt.out
开始jobtracker，登录到/usr/local/hadoop/libexec/../logs/hadoop-admin-jobtracker-vm-10 .vd.uk.pt.out
localhost：启动tasktracker，登录到/usr/local/hadoop/libexec/../logs/hadoop-admin-tasktracker-vm-10.vd.uk.pt.out
