Hadoop + Zookeeper + HBase Platform Construction

Articles on the establishment of the Hadoop + Zookeeper + HBase platform on the Internet can be said to be overwhelming and numerous. Here we will publish a very basic document left behind when we configure this platform, for your reference, you are welcome to raise any questions.

Start with the most basic configuration of the Hadoop platform.

L first, configure the Host Name and IP address, and the hosts file corresponding to the Host Name and IP address.

The IP address distribution of the final configured node is as follows:

Machine name	IP address
Master. Hadoop	192.168.117.122
Slave1.Hadoop	192.168.117.121
Slave2.Hadoop	192.168.117.120

1. view the current host name:

2. Modify the name of the current host:

Run the hostname command in the previous document.

Effect After reboot is found

The original modification of the host name with hostname only applies to this operation. After reboot, the host name will be restored to the HOSTNAME value in/etc/sysyconfig/network.

Modify the host name to continue. To modify the host name, you must switch to the root user. Normal users cannot modify the files in the/etc folder. It cannot be saved after modification. The prompt is read-only.

Switch users. Modify the HOSTNAME value again, and then reboot the host will be able to permanently modify the host name.

3. Modify the IP address of the current host

The IP address information is stored in the/etc/sysconfig/network-scripts folder and needs to be configured on the ifcfg-eth0 file. :

You can run the ifconfig command to view the changes.

You can skip the graph here.

4. Configure the hosts file

The/etc/hosts file is used to configure the DNS server information to be used by the host. When you connect to the host name in the cluster, view the IP address of the host name.

Add the following information to/etc/hosts, and configure the other two hosts as well.

192.168.117.122

Master. Hadoop

192.168.117.121

Slave1.Hadoop

192.168.117.120

Slave2.Hadoop

Modify the master node as follows:

Test results:

The configuration is successful.

5. Configure the 1-4 configuration in the same way to the Slave1.Hadoop and Slave2.Hadoop nodes.
