搭建Hadoop遇到的问题

<div class="iteye-blog-content-contain" style="font-size: 14px;">
<p>1、磁盘划分空间太少，造成复制文件复制不到虚拟机，解压文件不完整。</p>
<p>2、配置IP地址时在C:\Windows\System32\drivers\etc\hosts 没有添加主机名称和IP地址对应的映射</p>
<p>hosts文件如下：</p>
<p># Copyright (c) 1993-2009 Microsoft Corp.</p>
<p>#</p>
<p># This is a sample HOSTS file used by Microsoft TCP/IP for Windows.</p>
<p>#</p>
<p># This file contains the mappings of IP addresses to host names. Each</p>
<p># entry should be kept on an individual line. The IP address should</p>
<p># be placed in the first column followed by the corresponding host name.</p>
<p># The IP address and the host name should be separated by at least one</p>
<p># space.</p>
<p>#</p>
<p># Additionally, comments (such as these) may be inserted on individual</p>
<p># lines or following the machine name denoted by a '#' symbol.</p>
<p>#</p>
<p># For example:</p>
<p>#</p>
<p>#      102.54.94.97     rhino.acme.com          # source server</p>
<p>#       38.25.63.10     x.acme.com              # x client host</p>
<p> </p>
<p># localhost name resolution is handled within DNS itself.</p>
<p># 127.0.0.1       localhost</p>
<p># ::1             localhost</p>
<p>192.168.33.130      hadoop130</p>
<p>192.168.33.131      hadoop131</p>
<p>192.168.33.132      hadoop132</p>
<p>192.168.33.133      hadoop133</p>
<p>3.在Linux中同样配置好主机名称与IP地址的映射，检查网络是否畅通，我用的是Ubuntu</p>
<p>修改静态IP地址参见：<a href="https://blog.51cto.com/14163901/2418412">https://blog.51cto.com/14163901/2418412</a></p>
<p>4.在修改文件core-site.xml文件的时候路径没有写对，要写完整的路径，我只写了最后一部分，导致NameNode格式化失败。core-site.xml如下</p>
<p>&lt;?xml version="1.0" encoding="UTF-8"?&gt;</p>
<p>&lt;?xml-stylesheet type="text/xsl" href="configuration.xsl"?&gt;</p>

<p> </p>
<p>&lt;configuration&gt;</p>
<p>    &lt;property&gt;</p>
<p>        &lt;name&gt;fs.defaultFS&lt;/name&gt;</p>
<p>        &lt;value&gt;hdfs://hadoop131:9000&lt;/value&gt;</p>
<p>    &lt;/property&gt;</p>
<p> </p>
<p>    &lt;property&gt;</p>
<p>        &lt;name&gt;hadoop.tmp.dir&lt;/name&gt;</p>
<p>        &lt;value&gt;<span style="color: #ff0000;">/home/liyong/Desktop/software/hadoop/hadoop-3.1.3/data/tmp</span>&lt;/value&gt;</p>
<p>    &lt;/property&gt;</p>
<p> </p>
<p>&lt;/configuration&gt;</p>
<p>5、虚拟机没有连接上网络的时候可能是操作系统缺少某些组件没有安装，防火墙等问题，要么更换操作系统，要么添加组件。</p>
<p>欢迎学习交流。</p>
