Hadoop1.0.1安装部署(二)

PS:

/etc/hosts:

127.0.1.1       ubuntu-hadoop01
192.168.56.102  ubuntu-hadoop02
192.168.56.103  ubuntu-hadoop03

/etc/hostname:

ubuntu-hadoop01


3、安装并运行Hadoop

conf/hadoop-env.sh:

export JAVA_HOME=/usr/lib/jvm/jdk1.6.0_45


conf/core-site.xml:

<configuration>

        <property>

                <name>fs.default.name</name>

                <value>hdfs://ubuntu-hadoop01:9000</value>

        </property>

        <property>

                <name>hadoop.tmp.dir</name>

                <value>/home/grid/hadoop/tmp</value>

        </property>

</configuration>


conf/hdfs-site.xml:

<configuration>

        <property>

                <name>dfs.replication</name>

                <!-- 副本数 -->

                <value>1</value>

        </property>

</configuration>


conf/mapred-site.xml:

<configuration>

        <property>

                <name>mapred.job.tracker</name>

                <value>ubuntu-hadoop01:9001</value>

        </property>

</configuration>


conf/masters:

ubuntu-hadoop01


conf/slaves:

ubuntu-hadoop02

ubuntu-hadoop03




格式化Hadoop的文件系统HDFS:

输入命令:bin/hadoop namenode -format


启动Hadoop:

输入命令,启动所有进程:bin/start-all.sh


验证Hadoop安装是否成功:
