java-hdfs dfs -ls / 查询到的是本地文件目录，这是为什么？—

hdfs dfs -ls / 查询到的是本地文件目录，这是为什么？

已经配置了hadoop的环境变量，也source过了，但是只要不在hadoop/bin下面使用hdfs dfs -ls / 查询到的就是本地文件目录，并且报错：

Warning: fs.defaultFS is not set when running "ls" command.

如图：

但如果在bin目录下，显示正确，如图：

环境变量如图：

上网查了有人说core-site.xml有问题，我不是这个问题，配置文件如下：

请问有人知道这是怎么回事吗？

使用which hadoop和which hdfs查看是否指向正确位置，若不是，则删掉错误位置处的文件，重新source，然后一切正常

hadoop集群，hdfs dfs -ls / 目录出错: 搭建了一个hadoop集群，用hdfs dfs -ls /命令，列出的是本地系统的根目录。用hdfs dfs -ls hdfs://servicename/ 列出的目录才是hdfs上的目录，可能是什么原因？执行hive创建的目录也是在本地系统目录上。集群的配置如下集群规划：主机名 IP 安装的软件运行的进程 hadoop01 192.168.175.129 jdk、hadoop NameNode、DFSZKFailoverController(zkfc) hadoop02 192.168.175.127 jdk、hadoop NameNode、DFSZKFailoverController(zkfc) hadoop03 192.168.175.126 jdk、hadoop ResourceManager

1.liunx虚拟机安装后，虚拟机连接模式要选择host-only模式。然后分配IP(以hadoop01为例) DEVICE="eth0" BOOTPROTO="static" ### HWADDR="00:0C:29:3C:BF:E7" IPV6INIT="yes" NM_CONTROLLED="yes" ONBOOT="yes" TYPE="Ethernet" UUID="ce22eeca-ecde-4536-8cc2-ef0dc36d4a8c" IPADDR="192.168.175.129" ### NETMASK="255.255.255.0" ### GATEWAY="192.168.175.1" ### 2.修改主机名： vim /etc/sysconfig/network NETWORKING=yes HOSTNAME=hadoop01 ### 3.关闭防火墙： #查看防火墙状态 service iptables status #关闭防火墙 service iptables stop #查看防火墙开机启动状态 chkconfig iptables --list #关闭防火墙开机启动 chkconfig iptables off 4.免登录配置： #生成ssh免登陆密钥 #进入到我的home目录 cd ~/.ssh ssh-keygen -t rsa （四个回车）执行完这个命令后，会生成两个文件id_rsa（私钥）、id_rsa.pub（公钥）将公钥拷贝到要免登陆的机器上 cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys 或若报错ssh-copy-id: ERROR: No identities found，是因为找不到公钥路径,加上-i然后再加上路径即可则用 $ ssh-copy-id -i ~/.ssh/id_rsa.pub user@remote_ip 5.主机IP映射关系(/etc/hosts每台机器上都要配置全部映射关系) 192.168.175.129 hadoop01 192.168.175.127 hadoop02 192.168.175.126 hadoop03 192.168.175.125 hadoop04

/lichangwu/zookeeper-3.4.6/conf/ cp zoo_sample.cfg zoo.cfg vim zoo.cfg 修改：dataDir=/lichangwu/zookeeper-3.4.6/tmp 在最后添加： server.1=hadoop05:2888:3888 server.2=hadoop06:2888:3888 server.3=hadoop07:2888:3888 保存退出然后创建一个tmp文件夹 mkdir /lichangwu/zookeeper-3.4.6/tmp 再创建一个空文件 touch /lichangwu/zookeeper-3.4.6/tmp/myid 最后向该文件写入ID echo 1 > /lichangwu/zookeeper-3.4.6/tmp/myid 1.3将配置好的zookeeper拷贝到其他节点(首先分别在hadoop06、hadoop07根目录下创建一个lichangwu目录：mkdir /lichangwu) scp -r /lichangwu/zookeeper-3.4.6/ hadoop06:/lichangwu/ scp -r /lichangwu/zookeeper-3.4.6/ hadoop07:/lichangwu/ 注意：修改hadoop06、hadoop07对应/lichangwu/zookeeper-3.4.6/tmp/myid内容 itcast06： echo 2 > /lichangwu/zookeeper-3.4.6/tmp/myid itcast07： echo 3 > /lichangwu/zookeeper-3.4.6/tmp/myid 8.安装配置hadoop集群（在hadoop01上操作）: 2.1解压 tar -zxvf hadoop-2.4.1.tar.gz -C /lichangwu/ 2.2配置HDFS（hadoop2.0所有的配置文件都在$HADOOP_HOME/etc/hadoop目录下） #将hadoop添加到环境变量中 vim /etc/profile export

2.2.6修改slaves(slaves是指定子节点的位置，因为要在itcast01上启动HDFS、在itcast03启动yarn，所以itcast01上的slaves文件指定的是datanode的位置，itcast03上的slaves文件指定的是nodemanager的位置) hadoop05 hadoop06 hadoop07 2.2.7配置免密码登陆

2.5启动zookeeper集群（分别在hadoop05、hadoop06、hadoop07上启动zk） cd /lichangwu/zookeeper-3.4.6/bin/ ./zkServer.sh start #查看状态：一个leader，两个follower ./zkServer.sh status 2.6启动journalnode（分别在在hadoop05、hadoop06、hadoop07上执行） cd /lichangwu/hadoop-2.4.1 sbin/hadoop-daemon.sh start journalnode #运行jps命令检验，hadoop05、hadoop06、hadoop07上多了JournalNode进程 2.7格式化HDFS #在hadoop01上执行命令: hdfs namenode -format #格式化后会在根据core-site.xml中的hadoop.tmp.dir配置生成个文件，这里我配置的是/lichangwu/hadoop-2.4.1/tmp，然后将/lichangwu/hadoop-2.4.1/tmp拷贝到hadoop02的/lichangwu/hadoop-2.4.1/下。 scp -r tmp/ hadoop02:/lichangwu/hadoop-2.4.1/ 2.8格式化ZK(在hadoop01上执行即可) hdfs zkfc -formatZK 2.9启动HDFS(在hadoop01上执行) sbin/start-dfs.sh 2.10启动YARN(#####注意#####：是在hadoop03上执行start-yarn.sh，如果hadoop04上没有启动成功，则在hadoop04上再启动一次start-yarn.sh; 把namenode和resourcemanager分开是因为性能问题，因为他们都要占用大量资源，所以把他们分开了，他们分开了就要分别在不同的机器上启动) sbin/start-yarn.sh 到此，hadoop-2.4.1配置完毕，可以统计浏览器访问: http://192.168.175.129:50070 NameNode 'hadoop01:9000' (active) http://192.168.175.127:50070 NameNode 'hadoop02:9000' (standby)

Java学习的正确打开方式: 在博主认为，对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结，前三者博主将淋漓尽致地挥毫于这篇博客文章中，至于总结在于个人，实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍，博客次之，这又是一个层次了，这里暂时不提后面再谈。博主将为各位入门java保驾护航，各位只管冲鸭！！！上天是公平的，只要不辜负时间，时间自然不会辜负你。何谓学习？博主所理解的学习，它

程序员必须掌握的核心算法有哪些？: 由于我之前一直强调数据结构以及算法学习的重要性，所以就有一些读者经常问我，数据结构与算法应该要学习到哪个程度呢？，说实话，这个问题我不知道要怎么回答你，主要取决于你想学习到哪些程度，不过针对这个问题，我稍微总结一下我学过的算法知识点，以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的，并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构，当然，我也会整理一些看过

程序员接私活怎样防止做完了不给钱？: 首先跟大家说明一点，我们做 IT 类的外包开发，是非标品开发，所以很有可能在开发过程中会有这样那样的需求修改，而这种需求修改很容易造成扯皮，进而影响到费用支付，甚至出现做完了项目收不到钱的情况。那么，怎么保证自己的薪酬安全呢？我们在开工前，一定要做好一些证据方面的准备（也就是“讨薪”的理论依据），这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发

网页实现一个简单的音乐播放器（大佬别看。(⊙﹏⊙)）: 今天闲着无事，就想写点东西。然后听了下歌，就打算写个播放器。于是乎用h5 audio的加上js简单的播放器完工了。欢迎改进留言。演示地点跳到演示地点 html代码如下`<!DOCTYPE html> <html> <head> <title>music</title> <meta charset="utf-8"&gt

Python十大装B语法: Python 是一种代表简单思想的语言，其语法相对简单，很容易上手。不过，如果就此小视 Python 语法的精妙和深邃，那就大错特错了。本文精心筛选了最能展现 Python 语法之精妙的十个知识点，并附上详细的实例代码。如能在实战中融会贯通、灵活使用，必将使代码更为精炼、高效，同时也会极大提升代码B格，使之看上去更老练，读起来更优雅。 1. for - else 什么？不是 if 和 else 才

数据库优化 - SQL优化: 前面一篇文章从实例的角度进行数据库优化，通过配置一些参数让数据库性能达到最优。但是一些“不好”的SQL也会导致数据库查询变慢，影响业务流程。本文从SQL角度进行数据库优化，提升SQL运行效率。判断问题SQL 判断SQL是否有问题时可以通过两个表象进行判断：系统级别表象 CPU消耗严重 IO等待严重页面响应时间过长

2019年11月中国大陆编程语言排行榜: 2019年11月2日，我统计了某招聘网站，获得有效程序员招聘数据9万条。针对招聘信息，提取编程语言关键字，并统计如下：编程语言比例 rank pl_ percentage 1 java 33.62% 2 c/c++ 16.42% 3 c_sharp 12.82% 4 javascript 12.31% 5 python 7.93% 6 go 7.25% 7

通俗易懂地给女朋友讲：线程池的内部原理: 餐厅的约会餐盘在灯光的照耀下格外晶莹洁白，女朋友拿起红酒杯轻轻地抿了一小口，对我说：“经常听你说线程池，到底线程池到底是个什么原理？”我楞了一下，心里想女朋友今天是怎么了，怎么突然问出这么专业的问题，但做为一个专业人士在女朋友面前也不能露怯啊，想了一下便说：“我先给你讲讲我前同事老王的故事吧！” 大龄程序员老王老王是一个已经北漂十多年的程序员，岁数大了，加班加不动了，升迁也无望，于是拿着手里

JDK12 Collectors.teeing 你真的需要了解一下: 前言在 Java 12 里面有个非常好用但在官方 JEP 没有公布的功能，因为它只是 Collector 中的一个小改动，它的作用是 merge 两个 collector 的结果，这句话显得很抽象，老规矩，我们先来看个图(这真是一个不和谐的图????): 管道改造经常会用这个小东西，通常我们叫它「三通」，它的主要作用就是将 downstream1 和 downstre...

为啥国人偏爱Mybatis，而老外喜欢Hibernate/JPA呢？: 关于SQL和ORM的争论，永远都不会终止，我也一直在思考这个问题。昨天又跟群里的小伙伴进行了一番讨论，感触还是有一些，于是就有了今天这篇文。声明：本文不会下关于Mybatis和JPA两个持久层框架哪个更好这样的结论。只是摆事实，讲道理，所以，请各位看官勿喷。一、事件起因关于Mybatis和JPA孰优孰劣的问题，争论已经很多年了。一直也没有结论，毕竟每个人的喜好和习惯是大不相同的。我也看

项目中的if else太多了，该怎么重构？: 介绍最近跟着公司的大佬开发了一款IM系统，类似QQ和微信哈，就是聊天软件。我们有一部分业务逻辑是这样的 if (msgType = "文本") { // dosomething } else if(msgType = "图片") { // doshomething } else if(msgType = "视频") { // doshomething } else { // doshom...
