How to Create an YI-MapReduce Cluster Using a Custom Security Group?
1. Currently, only the China(Hongkong2) resource pool supports first-class nodes for the YI-MapReduce product. Future updates will be based on actual product rollouts.
2. Before creating a YI-MapReduce clusters, you need to establish a Virtual Private Cloud (VPC) and add the related security group rules in the first-class node resource pools such as China(Hongkong2) .
3. Refer to the Create a VPC section in the eSurfing Cloud - VPC product documentation. Create related VPC networks in the first-class node resource pool. By default, the CIDR block is "192.168.0.0/16".
4. After the above steps, you can find a default security group automatically added to the VPC created in the Control Center - Network Console - Access Control - Security Group menu. In addition, you can create custom security groups.
5. Before creating a YI-MapReduce clusters, refer to the Adding a Security Group Rule section in the eSurfing Cloud - Virtual Private Cloud product documentation. Add the following two inbound rules:
a. Allow remote 198.19.128.0/20 with Any protocol, and port range is 1-65535:
i. Authorization Policy: Choose Allow.
ii. Priority: Enter any number between 1-99.
iii. Protocol: Choose Any.
iv. Source Address: Choose IP, and enter 198.19.128.0/20.
v. Description: Fill in as needed.
b. Allow remote 192.168.0.0/24 (actual CIDR block address, depending on the VPC subnet CIDR block address created by the user) with Any protocol, and port range is Any:
i. Priority: Enter any number between 1-99.
ii. Authorization Policy: Choose Allow.
iii. Protocol: Choose Any.
iv. Source Address: Choose IP, enter 192.168.0.0/24 (actual CIDR block address, depending on the VPC subnet CIDR block address created by the user).
v. Description: Fill in as needed.
Description
After creating the VPC, the default security group automatically contains Rule a mentioned above, and the user needs to add Rule b. If the user uses a custom security group, ensure both Rule a and Rule b have been added.
How to change the login method for nodes within the YI-MapReduce cluster?
Changing is not available. The cluster login method chosen during the creation of the cluster cannot be altered later.
