没有要停止的Namenode、Datanode或辅助Namenode

Question

我在我的Ubuntu 12.04中安装了Hadoop，按照下面链接中的步骤操作。

http://www.bogotobogo.com/Hadoop/BigData_hadoop_Install_on_ubuntu_single_node_cluster.php

一切都已成功安装，当我运行start all时。sh只有部分服务正在运行。

wanderer@wanderer-Lenovo-IdeaPad-S510p:~$ su - hduse
Password:

hduse@wanderer-Lenovo-IdeaPad-S510p:~$ cd /usr/local/hadoop/sbin

hduse@wanderer-Lenovo-IdeaPad-S510p:/usr/local/hadoop/sbin$ start-all.sh

This script is Deprecated. Instead use start-dfs.sh and start-yarn.sh

hduse@wanderer-Lenovo-IdeaPad-S510p:/usr/local/hadoop/sbin$ jps
7940 Jps
7545 ResourceManager
7885 NodeManager

一旦我通过运行脚本停止服务，停止所有。嘘

我是Hadoop的新手，找不到这个问题。我在哪里可以找到Jobtracker和NameNode的日志文件，以便跟踪服务？

Answer 1

您必须为ssh设置无密码身份验证。hduse用户应该能够在没有密码的情况下通过ssh登录localhost。

Answer 2

如果你仔细看一看，开始一切。sh命令日志，您可以很容易地看到日志文件ş路径。尝试开始写入日志后的每个服务

localhost: starting namenode, logging to /usr/local/hadoop/logs/hadoop-hduse-namenode-wanderer-Lenovo-IdeaPad-S510p.out
ocalhost: starting datanode, logging to /usr/local/hadoop/logs/hadoop-hduse-datanode-wanderer-Lenovo-IdeaPad-S510p.out
0.0.0.0: starting secondarynamenode, logging to /usr/local/hadoop/logs/hadoop-hduse-secondarynamenode-wanderer-Lenovo-IdeaPad-S510p.out
starting resourcemanager, logging to /usr/local/hadoop/logs/yarn-hduse-resourcemanager-wanderer-Lenovo-IdeaPad-S510p.out
localhost: starting nodemanager, logging to /usr/local/hadoop/logs/yarn-hduse-nodemanager-wanderer-Lenovo-IdeaPad-S510p.out

Answer 3

如果不是ssh问题，请执行下一步：

检查hduser是否有权使用ls-ld目录写入hadoop_存储/hdfs/namenode和datanode目录

您可以通过sudo chmod 777 /hadoop_store/hdfs/namenode/
