本文详细介绍了Hadoop中的几个关键配置文件，包括core-site.xml（设置HDFS名称节点地址和文件存放目录）、hdfs-site.xml（配置副本数量和存储位置）、mapred-site.xml（指定MapReduce运行在YARN上）、yarn-site.xml（设置YARN日志存储目录）以及hive-site.xml（配置Hive元数据服务）。理解这些配置对于管理和优化Hadoop集群至关重要。

core-site.xml

hdfs-site.xml

mapred-site.xml

yarn-site.xml

hive-site.xml

hadoop中有几个比较重要的xml配置文件，如下图中绿色的高亮文件所示：

core-site.xml

1. 指定namenode的地址，就是如下页面的地址：

2. 用来指定使用hadoop时产生文件的存放目录

3. 用来设置检查点备份日志的最长时间

hdfs-site.xml

1. 指定hdfs保存数据的副本数量

2. 指定hdfs中namenode的存储位置

3. 指定hdfs中datanode的存储位置

mapred-site.xml

mapred是map reduce的缩写，这个配置主要是告诉hadoop以后MR(Map/Reduce)运行在YARN上。

yarn-site.xml

yarn-site.xml里有一个比较重要的配置，yarn的log文件存放目录就是在这个文件设置的。如果没有这个目录，是看不了yarn的log的。

注意，这个目录是指hdfs上的/tmp，不是本地的/tmp。

设置了这个文件后，再以yarn方式提交程序后，就能在hdfs上查看到log的目录：

hive-site.xml

还有一个hive-site.xml在/usr/local/hive/conf下，这里边配置了hive的元数据服务

HDFS：NameNode 是单点，一旦宕机，整个 HDFS 不可用。YARN：ResourceManager 是单点，一旦宕机，无法提交和管理新作业。HA 方案通过引入备用节点和共享元数据存储来解决这些问题。

dfs.datanode.du.reserved dfs.datanode.du.reserved表示的是datanode在对磁盘写数据的时候，保留多少空间给非HDFS使用。这个参数主要是为了防止磁盘空间被写满导致的HDFS异常。 最近遇到一个HDFS磁盘空间写满的问题，原因也很简单，就是因为dfs.datanode.du.reserved这个参数没有考虑到操作系统保留块空间的问题。 比如： 一块4T的盘，格式化完了以后剩下3.6T，去掉5%的系统保留空间，就剩下3.4T。 但是hbase是按照磁

进入此配置文件后，将“HOSTNAME”修改为“hadoop02”，这个名称可以随意修改，最好不要和之前已存在的虚拟机的主机名一样， 最后按Esc热键进入末行模式，输入“:wq”保存退出即可。“Web点击流日志”包含着网站运营很重要的信息，通过日志分析，我们可以知道网站的访问量，哪个网页访问人数最多，哪个网页最有价值，广告转化率、访客的来源信息，访客的终端信息等。获取方式：在页面预埋一段js程序，为页面上想要监听的标签绑定事件，只要用户点击或移动到标签，即可触发ajax请求到后台servlet程序，用。

5.1 提取四个默认配置文件第一步：将hadoop安装包解压到pc端的一个目录下，然后在hadoop-2.7.6目录下创建一个default目录，用于存储默认配置文件。第二步：进入hadoop的share目录中的doc子目录，搜索default.xml。将以下四个默认的xml文件copy到default目录中，方便以后查看5.2 $HADOOP_HOME/etc/hadoop/目录下的用户自定义配置文件5.3 属性的优先级6.1 配置core-site.xml文件参考：core-default.xml。

配置hadoop，主要是配置core-site.xml,hdfs-site.xml,mapred-site.xml三个配置文件，默认下来，这些配置文件都是空的，所以很难知道这些配置文件有哪些配置可以生效，上网找的配置可能因为各个hadoop版本不同，导致无法生效。浏览更多的配置，有两个方法:1.选择相应版本的hadoop,下载解压后，搜索*.xml,找到core-default.xml,hdfs-...

前言： 配置hadoop，主要是配置core-site.xml,hdfs-site.xml,mapred-site.xml三个配置文件。 上网找的配置可能因为各个hadoop版本不同，导致无法生效，这里需要经验积累。 参数繁多，不用过多纠结每个参数的含义，先照搬网上的参数， 用多几次，总会出现bug，需要反复调整的参数就是常用参数。 ±±±±±±±±±±±±±±±±±±±±±±±±±±±±±±±±...
