执行《Hadoop权威指南》范例3-2时报错 执行命令 export HADOOP_CLASSPATH=ch03-hdfs.jar hadoop FileSystemCat hdfs://localhost/user/liuzc/quangle.txt错误信息Exception in thread "main" java.net.ConnectException: Call From local

centos7环境下hadoop-2.7.3伪分布式搭建1、 修改主机名称###永久生效hostnamectl set-hostname hadoop012、下载解压将下载的hadoop-2.7.3.tar.gz解压到/usr/local目录下3、修改配置首先切换目录到/usr/local/hadoop-2.7.3/etc/hadoop下cd /usr/local/hadoop-2.7.3/etc

列表内容下载hadoop 地址http://mirrors.ibiblio.org/apache/hadoop/common/hadoop-2.7.3/hadoop-2.7.3.tar.gz解压hadoop-2.7.3.tar.gz到目录D:\software\hadoop-2.7.3配置环境变量 变量名：HADOOP_HOME 变量值：D:\software\hadoop-2.7.3

yarn-site.xml增加如下配置<!--配置历史服务器--><property> <name>mapreduce.jobhistory.address</name> <value>192.168.1.105:10020</value> </property> <property> <name>mapreduce.jobhistory.webapp.address</na

注：我的Hadoop版本是2.7.3 Hadoop安装参考我的博客 https://blog.youkuaiyun.com/tszxlzc/article/details/61635411下载hive,解压hive文件[root@hadoop01 local]# wget http://mirror.bit.edu.cn/apache/hive/hive-2.3.4/apache-hive-2.3...
