Click the node whose disk is to be replaced to go to the ECS console. Click Stop to stop the node. Contact Huawei Cloud technical support to replace the disk in the background. On the ECS console, click Start to start the node where the disk has been replaced.
Username admin/root Username for logging in to the cluster management page and the ECS node. Password - User password for logging in to the cluster management page and the ECS node. Confirm Password - Enter the user password again.
Step 4: Verify Jupyter Notebook access to MRS Step 1: Install the Client on a Node Outside the MRS Cluster Prepare a Linux ECS that does not belong to the MRS cluster, associate an EIP to the ECS, and install the cluster client by referring to Installing a Client on a Node Outside
You have prepared an ECS execution node and installed the MRS cluster client on the node. The node and the MRS cluster are in the same VPC and security group.
You need to specify the cluster type (for example, analysis or streaming), and set ECS instance specifications, number of instances, data disk type (common I/O, high I/O, and ultra-high I/O), and components to be installed, such as Hadoop, Spark, HBase, Hive, Kafka, and Storm, in
Perform the following operations to solve the issue: Install the MRS client on an ECS node. For details, see Using an MRS Client on Nodes Outside a Cluster. This operation uses the MRS client installation path /srv/client/ as an example.
The ECS console is displayed. In the upper right corner of the page, click Restart to restart the core node. On the Nodes tab of the cluster details page, select the core node, click Node Operation, and select Start All Roles. Repeat 1 to 11 to upgrade other core nodes.
You are familiar with how to use the ECS and the MRS development components. You have a certain understanding of the Maven build mode and usage methods. You already have some knowledge of the Java syntax.

The ECS page is displayed. Click Remote Login to log in to the Hive node. For MRS 3.x and later: Log in to the node where the Hive client has been installed as user root.
Added the monitoring on the exception that occurs when the ECS getSecuritykey API is called. Optimized the temporary AK/SK process. Resolved the issue of ResourceManager memory leakage. Fixed the error reported when the Hive union statement is used to merge small files.
Logging In to an MRS Cluster Node 04:21 Log in to the ECS node in the MRS cluster. MRS Cluster Scaling 04:36 Expand or shrink the MRS cluster. Configuring Auto Scaling for an MRS Cluster 03:42 Configure automatic scaling of Task nodes in the MRS cluster.
Billing Items The billing items of an MRS cluster consist of the MRS management service and IaaS infrastructure resources (ECS and EVS). For details about the billing factors and formulas for each billing item, see Billing Items.
The plaintext DK is only stored in the memory of the host running the ECS and is not stored persistently on the storage media. If the custom key is deleted or disabled in KMS, the disk encrypted using the key can still use the plaintext DK stored in the host memory.
