HBase installation on Windows 10

HBase Introduction

In the previous post we have been talking a little bit about Hadoop introduction and focused how to install Hadoop on Windows environment. In brief, Hadoop can perform only batch processing, and data will be accessed only in a sequential manner. It does mean one has to search the entire data-set even for the simplest of jobs.

A huge data-set when processed results in another huge data set, which should also be processed sequentially. At this point, a new solution is needed to access any point of data in a single unit of time (random access).

Apache HBase is an open source non-relational (NoSQL) distributed column-oriented database that runs on top of HDFS and real-time read/write access to those large data-sets. Initially, it was Google Big Table, afterwards it was re-named as HBase and is primarily written in Java, designed to provide quick random access to huge amounts of the data-set.

In brief, the HBase can store massive amounts of data from terabytes to petabytes and allows fast random reads and writes that cannot be handled by the Hadoop. Even relational databases (RDBMS) cannot handle a variety of data that is growing exponentially. 

HBase Installation

Here we will work through how to install HBase on Windows environment, HBase can be installed in three modes. The features of these modes are mentioned below.

[1] Standalone mode installation (No dependency on Hadoop system)

• This is default mode of HBase
• It runs against local file system
• It doesn't use Hadoop HDFS
• Only HMaster daemon can run
• Not recommended for production environment
• Runs in single JVM

[2] Pseudo-Distributed mode installation ( Single node Hadoop system + HBase installation)

• It runs on Hadoop HDFS
• All Daemons run in single node
• Recommend for production environment

[3] Fully Distributed mode installation ( Multi node Hadoop environment + HBase installation)

• It runs on Hadoop HDFS
• All daemons going to run across all nodes present in the cluster
• Highly recommended for production environment

Henceforward Hadoop should be pre-installed before installing HBase on windows. If you didn't install the Hadoop then visit previous post to install Hadoop on Windows 10.

I went through HBase 1.4.7 version, though you can use any stable version.

Hbase - Standalone mode installation

Here, we will go through the Standalone mode installation with Hbase on Windows 10.

STEP - 1: Extract the HBase file

Extract file hbase-1.4.7-bin.tar.gz and place under "D:\HBase", you can use any preferred location – 

[1] You will get again a tar file post extraction – 

[2] Go inside of hbase-1.4.7-bin.tar folder and extract again – 

[3] Copy the leaf folder “hbase-1.4.7” and move to the root folder "D:\HBase" and removed all other files and folders – 

STEP - 2: Configure Environment variable

Set the path for the following Environment variable (User Variables) on windows 10 – 

• HBASE_HOME - D:\HBase\hbase-1.4.7

This PC - > Right Click - > Properties - > Advanced System Settings - > Advanced - > Environment Variables 

STEP - 3: Configure System variable

Next onward need to set System variable, including Hive bin directory path – 

Variable: Path 

Value: 

• D:\HBase\hbase-1.4.7\bin

STEP - 4: Create required folders

Create some dedicated folders - 

1. Create folder "hbase" under “D:\HBase\hbase-1.4.7”.
2. Create folder "zookeeper" under “D:\HBase\hbase-1.4.7”.

For example - 

STEP - 5: Configured required files

Next, essential to configure two key files with minimal required details – 

• hbase-env.cmd
• hbase-site.xml

[1] Edit file D:/HBase/hbase-1.4.7/conf/hbase-env.cmd, mention JAVA_HOME path in the location and save this file.

@rem set JAVA_HOME=c:\apps\java

set JAVA_HOME=%JAVA_HOME

[2] Edit file D:/HBase/hbase-1.4.7/conf/hbase-site.xml, paste below xml paragraph and save this file.

<configuration>

<property>

<name>hbase.rootdir</name>

<value>file:///D:/HBase/hbase-1.4.7/hbase</value>

</property>

<property>

<name>hbase.zookeeper.property.dataDir</name>

<value>/D:/HBase/hbase-1.4.7/zookeeper</value>

</property>

<property>

<name> hbase.zookeeper.quorum</name>

<value>127.0.0.1</value>

</property>

</configuration>

All HMaster and ZooKeeper activities point out to this hbase-site.xml.

[3] Edit file hosts (C: /Windows/System32/drivers/etc/hosts), mention localhost IP and save this file.

127.0.0.1       localhost

 

STEP - 6: Start HBase

Here need to start HBase first - 

Open command prompt and change directory to “D:\HBase\hbase-1.4.7\bin" and type "start-hbase.cmd" to start HBase.

It will open a separate instances of cmd for following tasks – 

• HBase Master

STEP - 7: Validate HBase

Post successful execution of HBase, verify the installation using following commands –

• hbase –version
• jps

If we can see HMaster is in running mode, then our installation is okay.

STEP - 8: Execute HBase Shell

The standalone mode does not require Hadoop daemons to start. HBase can run independently. HBase shell can start by using "hbase shell" and it will enter into interactive shell mode – 

Congratulations, HBase installed !! 😊

STEP-9: Some hands on activities 

[1] Create a simple table

create 'student', 'bigdata'

[2] List the table has been created

list

[3] Insert some data to above created table

put ‘tablename’, ‘rowname’, ‘columnvalue’, ‘value’

put 'student', 'row1', 'bigdata:hadoop', 'hadoop couse'

[4] List all rows in the table

scan 'student'
