Building a pseudo-distributed HBASE cluster based on a pseudo-distributed Hadoop cluster

---

Preface

The purpose of this article is to build a pseudo-distributed HBASE cluster based on a pseudo-distributed Hadoop cluster, and build a pseudo-distributed Hadoop cluster environment tutorial to build a pseudo-distributed Hadoop cluster based on Baidu Smart Cloud Server

Operating environment

1、CentOS / 7.9 x86_64 (64bit)

2、jdk-8u281-linux-x64

3、hadoop-2.7.6

4、hbase-2.2.0

Unzip HBASE

cd /software/
tar -zxvf /download/hbase-2.2.0-bin.tar.gz
mv hbase-2.2.0/ hbase

Configure HBASE

Configure system variables

vi /etc/profile

Press insert at the end of the file and enter the following

#hbase
export HBASE_HOME=/software/hbase
export PATH=$HBASE_HOME/bin:$PATH

Press esc to enter: wd and press enter

test result

hbase version

If successful, the result is as follows

Configure the hbase-env.sh file

cd hbase/conf/
vi hbase-env.sh

export JAVA_HOME=/software/jdk
export HBASE_CLASSPATH=/software/hbase/conf
export HBASE_MANAGES_ZK=true

Press esc to enter: wd and press enter

Configure hbase-site.xml

cd hbase/conf/
vi hbase-site.xml

Press esc to enter: wd and press enter

mkdir -p /software/data/tmp/zookeeper-hbase

Configure the regionservers file

vi regionservers

Modify the contents of the file as:

localhost 

Start the cluster

You need to start Hadoop before starting HBASE. You can check with jps

to proceed to the next step as shown

cd /software/hbase/bin/
./start-hbase.sh

As shown in the figure, the startup is successful

View the cluster webUI interface

http://IP:16010/master-status

If successful, it is as shown in the figure

First experience with HBASE cluster

Start the client

hbase shell

View existing tables

list

The results are as follows:

Create a table tb with a column cluster mycf

create 'tb','mycf'  

test result

list

The results are as follows:
