1.2.2 大數據2.x 集羣安裝系列-- HDFS安裝配置

準備：

三臺虛擬機，JAVA，配置好網絡
參考系列1： https://blog.csdn.net/tanxiang21/article/details/104206881

1、配置

  <property>
        <name>fs.defaultFS</name>
        <value>hdfs://bigdata-pro01.kfk.com:9000</value>
    </property>

 <property>
        <name>dfs.replication</name>
        <value>2</value>
    </property>

2、啓動

bin/hdfs namenode -format
sbin/hadoop-daemon.sh start namenode
sbin/hadoop-daemon.sh start datanode

3、傳輸

scp -r hadoop-2.5.0/ [email protected]:/opt/modules/
scp -r hadoop-2.5.0/ [email protected]:/opt/modules/

4、啓動另外兩臺機器的datanode

sbin/hadoop-daemon.sh start datanode

5、創建一個文件試試

bin/hdfs dfs -mkdir -p /user/kfk/data/

http://bigdata-pro01.kfk.com:50070/explorer.html#/

bin/hdfs dfs -put /opt/modules/hadoop-2.5.0/etc/hadoop/core-site.xml /user/kfk/data

bin/hdfs dfs -text /user/kfk/data/core-site.xml
