According to the teacher's tutorial, on a virtual machine after installation, I created three machines here, in the allocation of Hadoop log in and use, the first step is no problems

But in the second step in the process, found in inspection network, I have the same results with the teacher don't
The teacher is the result of the

And I as a result of such

So when using password-less SSH commands on each other to such circumstance

Excuse me, as a laptop computer (no insert cable)

The appearance of the network configuration is correct?

CodePudding user response:

Close the firewall try

CodePudding user response:

Virtualbox?

CodePudding user response:

On line first and see how much is the machine's IP address, and then set fixed IP address for the virtual machine, and the machine's IP in the same network segment, I usually choose bridge network, bridge can let each virtual machine can ping each other, and NAT, function of virtual machine and the host could only ping,

CodePudding user response:

Classmates you first to win the CMD command box type ipconfig check off your IP is how many, may be caused by different segments, such as your computer may be 192.168.0. XXX, and 10.0.2 you. XXX is the can of course

CodePudding user response:

Configured to bridge network, do not use NAT

Turn off your other vitualBox Linux selinux firewall

CodePudding user response:

There, in the center of the network share to configure your virtual network adapter, gateway IP address to be consistent in the virtual machine network

CodePudding user response:

Firewall, Seliunx then you ping IP directly is better

It is caused by your IP address has changed, need to configure the static IP

I wrote a Hadoop distributed configuration, you can see can help you

CodePudding user response:

You can't match the teacher's gateway, check their own virtual machine card network information and then to own a gateway

CodePudding user response:

I configure Hadoop pseudo distributed, you can consult
(1) a Linux virtual machine configuration: https://blog.csdn.net/qq_41188880/article/details/106107279
(2) virtual machine installation Hadoop:https://blog.csdn.net/qq_41188880/article/details/106112638

CodePudding user response:

You can also try to use docker run a Hadoop cluster, this cluster, more convenient management and convenient than the zk

CodePudding user response:

To bridge network, NAT model, virtual machine can access the host machine, but the host machine don't have access to the virtual machine, so we can not transfer files,
