Code:Sudo adduser hadoop
Sudo chown-R hadoop: hadoop/usr/local/hadoop *
Sudo su-hadoop
Ssh-keygen-t rsa-P ""
Cat ~ /. Ssh/id_rsa.pub> ~ /. Ssh/authorized_keys
Sudo mkdir/usr/local/hadoop/tmp

4. Configure hadoop
Modify/usr/local/hadoop/etc/hadoop/hadoop-env.sh insert the following content before the export JAVA_HOME =$ {JAVA_HOME} line

Code:Export JAVA_HOME =/usr/lib/jvm/java-7-openjdk-amd64
Export HADOOP_CONF_DIR =/usr/local/hadoop/etc/hadoop

Modify/usr/local/hadoop/etc/hadoop/core-site.xml after <configuration> add

Code:<Property>
<Name> fs. default. name </name>
<Value> hdfs :/// localhost: 9000 </value>
</Property>
<Property>
<Name> hadoop. tmp. dir </name>
<Value>/usr/local/hadoop/tmp </value>
</Property>

5 Format hadoop

Code:/Usr/local/hadoop/bin/hadoop namenode-format

6. Start hadoop

Code:/Usr/local/hadoop/sbin/start-all.sh

7. Test hadoop

Code:/Usr/local/hadoop/bin/hadoop fs-df

#8 stop hadoop
#/Usr/local/hadoop/sbin/stop-all.sh

9. Exit hadoop users

HBASE

1 installation:

Code:Wget http://mirror.bit.edu.cn/apache/hbase/stable/hbase-0.98.6-hadoop2-bin.tar.gz
Tar xzf hbase-0.98.6-hadoop2-bin.tar.gz
Sudo mv hbase-0.98.6-hadoop2/usr/local/
Cd/usr/local/
Sudo ln-s hbase-0.98.6-hadoop2/hbase
Sudo chown-R hadoop: hadoop hbase *

2 configuration:

Code:Sudo su-hadoop

Edit/usr/local/hbase/conf/hbase-env.sh to find the row for export JAVA_HOME and insert the following:

Code:Export JAVA_HOME =/usr/lib/jvm/java-7-openjdk-amd64
Export HBASE_HOME =/usr/local/hbase

Edit/usr/local/hbase/conf/hbase-site.xml insert after the <configuration> line:

Code:<Property>
<Name> hbase. rootdir </name>
<Value> hdfs: /localhost: 9000/hbase </value>
</Property>
<Property>
<Name> dfs. replication </name>
<Value> 1 </value>
</Property>

3. Start:

Code:/Usr/local/hbase/bin/start-hbase.sh

4 Test:

Code:/Usr/local/hbase/bin/hbase shell
Hbase (main): 001: 0> status

#5 close:
#/Usr/local/hbase/bin/stop-hbase.sh
