安装教程可以看我之前的博客
我的系统是Ubuntu 21.04 KDE ，但只要你的系统是ubuntu，这些命令就应该是通用的。
非分布式配置（单机模式）
summary
# 把hadoop的所有配置xml文件作为输入，复制到新建的input文件夹里
mkdir ./input && cp /opt/software/hadoop-3.3.1/etc/hadoop/*.xml ./input
# 运行grep例子，将input文件中的所有文件作为输入，筛选符合表达式dfs[a-z.]+的单词并统计出现的次数，输出到output文件夹
hadoop jar /opt/software/hadoop-3.3.1/share/hadoop/mapreduce/hadoop-mapreduce-examples-3.3.1.jar grep ./input ./output 'dfs[a-z.]+'
# 查看结果
cat ./output/*
ls ./output/
执行成功后如下所示，输出了作业的相关信息，输出的结果是符合正则的单词 dfsadmin 出现了1次
[email protected]:~/test$ cat ./output/*
1 dfsadmin

# 一些详情
An example program must be given as the first argument.
Valid program names are:
aggregatewordcount: An Aggregate based map/reduce program that counts the words in the input files.
aggregatewordhist: An Aggregate based map/reduce program that computes the histogram of the words in the input files.
bbp: A map/reduce program that uses Bailey-Borwein-Plouffe to compute exact digits of Pi.
dbcount: An example job that count the pageview counts from a database.
distbbp: A map/reduce program that uses a BBP-type formula to compute exact bits of Pi.
grep: A map/reduce program that counts the matches of a regex in the input.
join: A job that effects a join over sorted, equally partitioned datasets
multifilewc: A job that counts words from several files.
pentomino: A map/reduce tile laying program to find solutions to pentomino problems.
pi: A map/reduce program that estimates Pi using a quasi-Monte Carlo method.
randomtextwriter: A map/reduce program that writes 10GB of random textual data per node.
randomwriter: A map/reduce program that writes 10GB of random data per node.
secondarysort: An example defining a secondary sort to the reduce.
sort: A map/reduce program that sorts the data written by the random writer.
sudoku: A sudoku solver.
teragen: Generate data for the terasort
terasort: Run the terasort
teravalidate: Checking results of terasort
wordcount: A map/reduce program that counts the words in the input files.

到test文件夹里，把hadoop的所有配置xml文件作为输入，复制到新建的input文件夹里
[email protected]:~/test$ mkdir ./input && cp /opt/software/hadoop-3.3.1/etc/hadoop/*.xml ./input
运行grep例子，将input文件中的所有文件作为输入，筛选符合表达式dfs[a-z.]+的单词并统计出现的次数，输出到output文件夹
[email protected]:~/test$ hadoop jar /opt/software/hadoop-3.3.1/share/hadoop/mapreduce/hadoop-mapreduce-examples-3.3.1.jar grep ./input ./output 'dfs[a-z.]+'

伪分布式配置
summary
Hadoop 可以在单节点上以伪分布式的方式运行，Hadoop 进程以分离的 Java 进程来运行，节点既作为 NameNode 也作为 DataNode，同时，读取的是 HDFS 中的文件。
Hadoop 的配置文件位于/usr/local/hadoop/etc/hadoop/ 中，伪分布式需要修改2个配置文件 core-site.xml 和 hdfs-site.xml 。Hadoop的配置文件是 xml 格式，每个配置以声明 property 的 name 和 value 的方式来实现。
将core-site.xml的
<configuration>
</configuration>
替换为
<configuration>
<property>
<name>hadoop.tmp.dir</name>
<value>file:/usr/local/hadoop/tmp</value>
<description>Abase for other temporary directories.</description>
</property>
<property>
<name>fs.defaultFS</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>
将hdfs-site.xml的
<configuration>
</configuration>
替换为
<configuration>
<property>
<name>hadoop.tmp.dir</name>
<value>file:/usr/local/hadoop/tmp</value>
<description>Abase for other temporary directories.</description>
</property>
<property>
<name>fs.defaultFS</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>
Hadoop配置文件说明
Hadoop 的运行方式是由配置文件决定的（运行 Hadoop 时会读取配置文件），因此如果需要从伪分布式模式切换回非分布式模式，需要删除core-site.xml 中的配置项。
此外，伪分布式虽然只需要配置 fs.defaultFS 和 dfs.replication 就可以运行（官方教程如此），不过若没有配置hadoop.tmp.dir 参数，则默认使用的临时目录为/tmp/hadoo-hadoop，而这个目录在重启时有可能被系统清理掉，导致必须重新执行 format才行。所以我们进行了设置，同时也指定dfs.namenode.name.dir 和 dfs.datanode.data.dir，否则在接下来的步骤中可能会出错。
