    Hi there,

    Apache HBase can be installed in the following three modes :

    1. Standalone mode
    2. Pseudo Distributed mode
    3. Fully Distributed mode

    This blog is to setup HBase in standalone mode on your Ubuntu machine without any hassle. You can search for blogs on Pseudo Distributed or Fully Distributed mode installation of HBase on Findnerd.

    Prerequisite for HBase installation

    • Java >= 7

    Use this reference to install Java on your machine

    http://findnerd.com/account#url=/list/view/Install-Oracle-JDK-with-apt-get/2944/

    Apache Zookeeper should be installed on machine, to know about Zookeeper follow this tutorial

    http://findnerd.com/account/#url=/list/view/Apache-Zookeeper-installation-in-Ubuntu-for-Standalone-mode/20129/

    Ensure that both are properly installed on your machine.

     

    Installation part for Apache HBase.

    Download a stable release form apache mirrors for HBase. In my case I downloaded hbase-1.1.5-bin.tar.gz to ~/Downloads.


    Extract the downloaded package

    tar -zxvfhbase-1.1.5-bin.tar.gz

     

    Move the extracted package to a location of your choice, I picked /usr/local/hbase

    sudo mv ~/Downloads/hbase-1.1.5/ /usr/local/hbase

     

    Open your .bashrc file an append the hbase variables into it.

    gedit ~/.bashrc
    #hbase
    export HBASE_HOME=/usr/local/hbase
    export HBASE_CONF_DIR=$HBASE_HOME/conf
    export HBASE_CLASS_PATH=$HBASE_CONF_DIR
    export PATH=$HBASE_HOME/bin:$PATH

     

    save your .bashrc and execute the source command on it.

    source ~/.bashrc

     

    Go to hbase's conf directory

    cd /usr/local/hbase/conf/

     

    Open hbase-env.sh and put your Java path here .

    sudo gedit hbase-env.sh

    remove comment on the Java Home variable and update your Java home path.

     

    Now edit your hbase-site.xml

    sudo gedit hbase-site.xml

    put the following lines inside <configuration></configuration> tags.

    //Set the path where you want HBase to store its file
       <property>
          <name>hbase.rootdir</name>
          <value>file:///home/{username}/HBase/HFiles</value>
       </property>
    	
       //set the path defined for zookeeper files earlier.
       <property>
          <name>hbase.zookeeper.property.dataDir</name>
          <value>/home/{username}/zookeeper</value>
       </property>

     

    now the stage is set and you only need to start HBase.

    start-hbase.sh

     

    to use hbase shell execute

    start-hbase.sh

    and HBase will provides Extensible jruby-based (JIRB) shell as a feature to execute some commands

     

    Now i will create a table naming testTable

    create 'testTable','info','content'

    and its output will be

    0 row(s) in 3.4630 seconds
    
     => Hbase::Table - testTable 

     

    to list all the table use list

    list

    its output will contain your newly created testTable

    TABLE                                                                                                                                                     
    blog                                                                                                                                                      
    test                                                                                                                                                      
    testTable                                                                                                                                                 
    3 row(s) in 0.0730 seconds
    
     => ["blog", "test", "testTable"]

     

    to put values inside your table

    put 'testTable','row1','info:auther','Abhishek'
    put 'testTable','row1','content:xyz','Abhishek'
    put 'testTable','row2','content:xyz','abcd'

     

    to scan your table

    scan 'testTable'

    and the response will be

    ROW                                     COLUMN+CELL                                                                                                       
     row1                                   column=content:xyz, timestamp=1464173663187, value=Abhishek                                                       
     row1                                   column=info:auther, timestamp=1464173632288, value=Abhishek                                                       
     row2                                   column=content:xyz, timestamp=1464173714201, value=abcd                                                           
    2 row(s) in 0.0210 seconds
    

     

    to exit from shell type exit and return

    exit
    

     

    to stop hbase

    stop-hbase.sh

    You can use the HBase GUI using the address http://localhost:16010/ while HBase server is running. A snapshot of HBase GUI is given here.

     

    HBase Java API will be explained in further blogs.

    Thanks,
