Configuring Storage-Compute Decoupling Using IAM Agencies Create an ECS agency with OBS access permissions. You need to create an ECS agency with OBS access permissions. The ECS agency is used to automatically obtain temporary AK/SK to access OBS.
Installing a Client on a Node Outside a Cluster Create an ECS that meets the following requirements: A Linux ECS has been prepared. For details about the supported OS of the ECS, see Table 2.
An agency allows ECS or BMS to manage MRS resources. You can configure an agency of the ECS type to automatically obtain the AK/SK to access OBS. For details, see Interconnecting an MRS Cluster with OBS Using an IAM Agency.

Cause Analysis The user's MRS cluster uses enterprise project A (with MRS FULLACCESS and ECS FULLACCESS permissions). The VPC uses enterprise project B. The security group uses enterprise project A. No permissions are configured for the IAM user group.
However, if you modify MRS cluster tags on the ECS or EVS console, the modification will not be synchronized to MRS. To ensure tag consistency, do not modify MRS cluster tags on the ECS or EVS console. You can add a maximum of 20 tags to a cluster.
fs.obs.security.provider Implementation method of obtaining the key for accessing the OBS file system Value options are as follows: com.huawei.mrs.MrsObsCredentialsProvider: obtains a credential through an MRS agency. com.obs.services.EcsObsCredentialsProvider: obtains an AK/SK through the ECS
For instance, to access the HDFS web UI, you must first create an ECS instance for remote login. This adds complexity to accessing the UI.
On the Nodes tab, click the name of a master node in the master node group to log in to the ECS console. Click the EIPs tab and click Bind EIP to bind an EIP to the ECS. Log in to the master node and run the pip3 install command to install Python. Parent topic: Cluster Management
