Cloudera hadoop

本文介绍了Cloudera hadoop - 守护程序进程未运行的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在自学Hadoop并开始安装 Cloudera QuickStart 在运行CENT OS的VMware工作站上。 我认为Quickstart VM具有预定义的大部分配置。我是否需要设置任何其他配置来设置数据和名称节点？原因是当我输入JFS时我只得到

I'm self learning Hadoop and started of with installing Cloudera QuickStart on a VMware Workstation running CENT OS. I was under the impression that Quickstart VM has most the of configurations predefined. Do I need to set up any other configurations to set up data and name node? Reason being when I type JFS I get only

[cloudera@quickstart bin]$ jps 9480 RunJar 18607 Jps 6952 org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar

我没有看到任何数据节点也没有命名节点。我在网上查找了它，解决方案是使用start-all.sh启动守护进程。但我收到错误

I don't see any data nodes nor name nodes.I looked it up online and solution was to start the daemons using start-all.sh. But I get an error

[cloudera@quickstart hadoop]$ start-all.sh bash: start-all.sh: command not found

另一轮研究让我进入这个 正如那个答案所建议的，当我运行bin / hadoop namenode -format

Another round of research landed me in this As suggested in that answer, when I ran bin/hadoop namenode -format

[cloudera@quickstart hadoop]$ bin/hadoop namenode -format bash: bin/hadoop: No such file or directory

我陷入了无处不在的地方，自学的动力变得非常低。请帮忙提出建议并提高我的精神。 PS：我是Hadoop的极端初学者，所以如果问题请不要苛刻我看起来很愚蠢:) 我尝试过： 我找了几个社区寻求解决方案，并在问题中嵌入了这些链接。

I'm stuck in the middle of nowhere with motivation for self study getting really low. Please help with a suggestion and raise up my spirits. P.S.: I'm an extreme beginner on Hadoop, so please don't be harsh on me if the question looks stupid to you :) What I have tried: I have looked up several communities for solution and have embedded those links in the question.

start-all。 sh bash：start-all.sh：命令未找到 start-all.sh bash: start-all.sh: command not found

Another round of research landed me in this As suggested in that answer, when I ran bin/hadoop namenode -format

[cloudera@quickstart hadoop]

bin / hadoop namenode -format bash：bin / hadoop：没有这样的文件或目录 bin/hadoop namenode -format bash: bin/hadoop: No such file or directory
