Does YI-MapReduce Support Modification of the CIDR Block?

Currently, YI-MapReduce does not support modification of the CIDR block for nodes within a cluster. Therefore, we advise customers to partition the CIDR block based on business needs before activating the YI-MapReduce cluster. Also, ensure the availability of suitable resources in other eSurfing Cloud products, such as the Virtual Private Cloud (CT-VPC).

The /var/log directory on nodes in the YI-MapReduce cluster contains essential log data related to operations of the operating system, security, and application and audit logs of instances of various components deployed in the YI-MapReduce cluster. This information can assist customers in identifying issues with the cloud host system and provide security auditing for the YI-MapReduce component cluster.

•        It is not recommended to clean up the system log files mentioned above. This is a high-risk operation that may lead to the failure or unavailability of the Elastic Cloud Server.

•        For the application and audit logs of the YI-MapReduce cluster mentioned above, you should consider the need for cleanup. If cleanup is necessary, you should prioritize deleting older historical logs.

Can I Modify the IP Address of the Nodes in the YI-MapReduce cluster?

Currently, modifying the IP address of nodes within the YI-MapReduce cluster is not possible.
