Ubuntu上使用Hadoop 2.x 二 配置single node server
假定已经用hduser登录，现在开始设置环境变量, 将下面的内容添加到~/.bashrc，
#Hadoop variables export JAVA_HOME=/usr/lib/jvm/java-7-oracle/ export HADOOP_INSTALL=/usr/local/hadoop export PATH=$PATH:$HADOOP_INSTALL/bin export PATH=$PATH:$HADOOP_INSTALL/sbin export HADOOP_MAPRED_HOME=$HADOOP_INSTALL export HADOOP_COMMON_HOME=$HADOOP_INSTALL export HADOOP_HDFS_HOME=$HADOOP_INSTALL export YARN_HOME=$HADOOP_INSTALL export HADOOP_CONF_DIR="$HADOOP_COMMON_HOME/etc/hadoop" ###end of paste
继续修改文件/usr/local/hadoop/etc/hadoop/hadoop-env.sh里面的JAVA_HOME
# The java implementation to use. export JAVA_HOME=/usr/lib/jvm/java-7-oracle/
退出后，重新用hduser登录，然后执行命令检查：
hduser@hm1:~$ hadoop version Hadoop 2.2.0 Subversion https://svn.apache.org/repos/asf/hadoop/common -r 1529768 Compiled by hortonmu on 2013-10-07T06:28Z Compiled with protoc 2.5.0 From source with checksum 79e53ce7994d1628b240f09af91e1af4 This command was run using /usr/local/hadoop/share/hadoop/common/hadoop-common-2.2.0.jar
现在hadoop已经安装好了。下面为启动进行配置。
在文件/usr/local/hadoop/etc/hadoop/core-site.xml文件中将<configuration></configuration>中添加配置。
仍使用hadoop 1.0的hdfs工作模式
<configuration>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost:9000</value>
</property>
</configuration>
添加下面的配置到文件/usr/local/hadoop/etc/hadoop/yarn-site.xml
制定启动时node manager的aux service使用shuffle server.
<configuration>
<!-- Site specific YARN configuration properties -->
<property>
<name>yarn.nodemanager.aux-services</name>
<value>mapreduce.shuffle</value>
</property>
<property>
<name>yarn.nodemanager.aux-services.mapreduce.shuffle.class</name>
<value>org.apache.hadoop.mapred.ShuffleHandler</value>
</property>
</configuration>
修改/usr/local/hadoop/etc/hadoop/mapred-site.xml文件
cp mapred-site.xml.template mapred-site.xml
指定yarn为采用的map reduce框架名称
<configuration>
<property>
<name>mapreduce.framework.name</name>
<value>yarn</value>
</property>
</configuration>
hduser@hm1:/usr/local/hadoop/etc/hadoop$ cd ~/ hduser@hm1:~$ mkdir -p mydata/hdfs/namenode hduser@hm1:~$ mkdir -p mydata/hdfs/datanode
编辑/usr/local/hadoop/etc/hadoop/hdfs-site.xml文件
<configuration>
<property>
<name>dfs.replication</name>
<value>1</value>
</property>
<property>
<name>dfs.namenode.name.dir</name>
<value>file:/home/hduser/mydata/hdfs/namenode</value>
</property>
<property>
<name>dfs.datanode.data.dir</name>
<value>file:/home/hduser/mydata/hdfs/datanode</value>
</property>
</configuration>
