How to Install and Download Cloudera QuickStart VM

• You would need a virtual machine like VMware or Oracle VirtualBox on your system before configuring the Cloudera Virtual Machine.
•  In this instance, we are setting up the Cloudera QuickStart VM with Oracle VirtualBox.
• Click on the following link to download and install Oracle VirtualBox on your operating system:Oracle VirtualBox.
• Click on "File" and then "Import Appliance" to configure your Oracle VirtualBox Manager to use the Cloudera QuickStart VM.

• By checking through your downloads, select the QuickStart VM image. Select "Open" and then "Next." After seeing the requirements, select "Import." The virtual disc image import will then begin. Enter your VM box as a vmdk file.
• Once this is done, we have to change the specifications of the machines to use. Here, we are giving 2 CPU cores and 5GB RAM. Wait for a while, as the importing finishes. The next step is to go ahead and set up a Cloudera QuickStart VM for practice. Once the importing is complete, you can see the Cloudera QuickStart VM on the left side panel.

• Now, to give more RAM and CPU cores, click on ‘Settings’, followed by ‘System’, and increase the RAM to 5GB. Click on the processor and assign 2 CPU cores. Subsequently, select ‘Network’. The Adapter 1 settings should be NAT by default. Click on ‘OK’ next.
• You must now start the computer so that it activates the Cloudera QuickStart VM and uses 2 CPU cores and 5GB of RAM.
• The next action is to proceed and press the top-right "Start" button to start the machine.
• When your device turns on, it will seem as follows:

• We must then carry out a few actions in order to enter the admin console. Click the terminal icon at the top of the desktop screen, then put the following into it:

• You can close the terminal once you verify that your HDFS access is functioning properly. Then, you must select the 'Launch Cloudera Express' icon from the following menu.

• When you click the express icon, a screen with the following instruction will appear:

• The command needs to be copied and executed on a different terminal. Therefore, launch a new terminal and enter the command listed below to shut off the Cloudera-based services. After the services have been restarted, you can access your admin console.
• Client configurations have also been deployed as a result of the setting of our deployment. The Cloudera Management Service, which uses a username and password to access the Cloudera QuickStart admin dashboard, has also been restarted.
• Continue to launch the browser and modify the port setting to 7180.
• The Cloudera Manager can be accessed by entering your username and password.

• If you don't provide the Cloudera cluster adequate RAM, it can slow down because Cloudera uses a lot of CPU and memory. Therefore, it is always advised to discontinue or delete any services you no longer require. 
• To remove a service, click on the drill-down button next to it and then choose delete.

• It is necessary to eliminate all dependencies for each service before eliminating it. When you need them, you may always add services to your cluster. Additionally, you can use that to resolve various setting issues.
• You may correct any configuration or health issues in your cluster with Cloudera Manager.

• Now is the time to restart the services. It will make sure that Hue, a web interface, or Cloudera QuickStart Terminal, where you can enter commands, can access the cluster.
• You can change to the admin user, which is an HDFS user. Unless you have specified a password, this typically does not have one. You may now enter any HDFS command into the terminal to get the output.
