闲话不多讲,主要为方便想学hadoop但没有多余机器的朋友
(1)core-site.xml配置
<configuration> <property> <name>fs.default.name</name> <value>hdfs://localhost:9000</value> </property> </configuration>
(2)hdfs.site.xml
<configuration> <property> <name>dfs.replication</name> <value>1</value> </property> <property> <name>dfs.permissions</name> <value>false</value> </property> <property> <name>hadoop.tmp.dir</name> <value>/home/hadoop/hadooptmp</value> </property> <property> <name>dfs.data.dir</name> <value>/home/hadoop/hadoopdata</value> </property> <property> <name>dfs.name.dir</name> <value>/home/hadoop/hadoopname</value> </property> </configuration>
(3)mapred-site.xml
<configuration> <property> <name>mapred.job.tracker</name> <value>localhost:9001</value> </property> </configuration>
(4)hdfs.env.sh
export JAVA_HOME=/home/hadoop/jdk
以上是伪分布式的配置
