Ubuntu Installation hadoop2.6

One: stand-alone version

1.sudo gedit ~/.BASHRC Join JDK Path

#HADOOP VARIABLES START  export Java_home=/usr/lib/jvm/java-1.7.0-openjdk-amd64export hadoop_install=/home/ sendi/hadoop-2.6.0 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_common_lib_native_dir= $HADOOP _install/lib/ Native  export hadoop_opts= "-djava.library.path= $HADOOP _install/lib"  #HADOOP VARIABLES END

Ubantu the JDK path can be obtained using the following command:

Update-alternatives--config Java

2. Execute the following command to make the change effective:

SOURCE ~/.BASHRC

3. Modify the configuration of the hadoop-env.sh:

sudo gedit/usr/local/hadoop/etc/hadoop/hadoop-env.sh

Find Java_home instead of:

/usr/lib/jvm/java-1.7.0-openjdk-amd64

Then add a line of code below:

Export hadoop_opts= "-djava.library.path= $HADOOP _prefix/lib: $HADOOP _prefix/lib/native"

Second: pseudo-distributed:

1.sudo Gedit/usr/local/hadoop/etc/hadoop/core-site.xml

<configuration> <property>     <name>hadoop.tmp.dir</name>     <value>/home/sendi /hadoop-2.6.0/tmp</value>     <description>abase for other temporary directories.</description>   </property>   <property>     <name>fs.defaultFS</name>     <value>hdfs:/ /localhost:9000</value> </property></configuration>

2.sudo GEDIT/USR/LOCAL/HADOOP/ETC/HADOOP/MAPRED-SITE.XM

<configuration>      <property>               <name>mapred.job.tracker</name>              <value> localhost:9001</value>         </property>   </configuration>

3.sudo Gedit/usr/local/hadoop/etc/hadoop/yarn-site.xml

<configuration>  <property>   <name>mapreduce.framework.name</name>   <value >yarn</value>  </property>  <property> <name>yarn.nodemanager.aux-services </name>   <value>mapreduce_shuffle</value>  </property>  

4.sudo Gedit/usr/local/hadoop/etc/hadoop/hdfs-site.xml

<configuration>   <property>          <name>dfs.replication</name>          <value>1< /value>      </property>      <property>          <name>dfs.namenode.name.dir</name>          <value>file:/home/sendi/hadoop-2.6.0/dfs/name</value>      </property>   </configuration >

5.sudo gedit/usr/local/hadoop/etc/hadoop/masters 添加：localhost

6.sudo gedit/usr/local/hadoop/etc/hadoop/slaves  添加：localhost

7. Initializing file system HDFs

Bin/hdfs Namenode-format  

8. Start
