1. Ensure the cross-region network of the CCN product requires public network bandwidth
DataInLong resource groups need to be in the same VPC network as the customer's database, accessed via the intranet. If the integration resource group and the database are in VPCs of different regions, the network needs to be connected via CCN.
CCN, for convenience of testing, has a default 10Kb traffic allowance, suitable only for small data synchronization and network testing. For performance testing and production tasks, please purchase bandwidth to avoid data synchronization being limited by network bandwidth.
2. Hive On CHDFS Table Write Error: Permission denied: No access rules matched
Error message:
Reason:
DataInLong resource group is a fully managed resource group. The export subnet of the resource group is not within the customer's VPC internal subnet, and the security group needs to be opened for the DataInLong resource group.
Please authorize the CHDFS permission ID of the integrated resource group at the CHDFS mount point.
Solution:
Open the page: API 3.0 Explorer, fill in the parameters, where MountPointId is the customer's CHDFS mount point, and AccessGroupIds.N is the CHDFS permission ID of the DataInLong resource group (note, permission IDs vary by region).
