总环境配置一、预装环境配置1. Homebrew
2. JAVA
二、配置 SSH为了保证远程登录管理 Hadoop 及 Hadoop 节点用户共享的安全性,Hadoop 需要配置使用 SSH 协议
2. 配置伪分布式 Hadoop(1)配置 hadoop-env.sh
(2) 配置 yarn-env.sh
(3)配置 core-site.xml
6.可视化查看
四、总结其实配置起来,如果按照上面的话,其实很快,但摸索的时候坑多,网速什么,路径什么,没事就会崩一崩。 环境搭好,继续撸理论,与一些也做这个的朋友们讨论了一下,还是要补一下统计学的知识,如果部门谁有兴趣,可以试一试哦。 |

很详细,太赞了! 我按楼主的步骤操作,到./start-dfs.sh就会出点问题,出现如下现象: “2016-09-04 15:24:50.474 java[15275:613152] Unable to load realm info from SCDynamicStore” 在stackoverflow上查到,将“hadoopp-env.sh”中楼主修改的那句修改成如下可修复: HADOOP_OPTS='${HADOOP_OPTS} -Djava.security.krb5.realm= -Djava.security.krb5.kdc=' HADOOP_OPTS='${HADOOP_OPTS} -Djava.security.krb5.conf=/dev/null' 这个不算问题。 现在遇到个问题,运行完start-dfs和start-yarn后,jps后出现如下 14572 ResourceManager 14242 NameNode 15585 Jps 4432 14450 SecondaryNameNode 14670 NodeManager 也就是DataNode没有显示出来,实际上4432应该是DataNode吧,不知怎么回事。 最后的示例也运行不了,显示如下问题: org.apache.hadoop.ipc.RemoteException(java.io.IOException): File /user/yjgu/QuasiMonteCarlo_1472973018410_433909577/in/part0 could only be replicated to 0 nodes instead of minReplication (=1). There are 0 datanode(s) running and no node(s) are excluded in this operation. 请问楼主对这清不清楚,知道怎么解决吗。 谢谢。 |

mac 上可以用普通的tar.gz的linux包安装运行hadoop么?楼主试过没有? |
commented Mar 27, 2017
ssh-keygen -t dsa -P ' -f ~/.ssh/id_dsa cat 我执行上面这个好像不能免密,还是得输入密码,最后将dsa换成rsa就可以了 |

感谢楼主教程, 刚又踩了一个坑, namenode跑不起来, 后来查看到, namenode用到的端口被占了 |
commented Jun 28, 2017
job 一直处理Running 状态有遇到过?

1楼应该是datanode没有启动,所以例子也无法运行,可能是namenode跟datanode的id不一致,你是否多次格式化过namenode |

一直提示18/09/16 18:45:26 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform.. using builtin-java classes where applicable |
