For details about how to use a client on a master or core node in a cluster, see Installing a Client. For details about how to use a client on a node outside a cluster, see Installing a Client. Log in to FusionInsight Manager.
Check whether appId in the request path (URL) is correct. 500 50252 Internal server error. An internal server error occurs. Recommended handling: An internal error occurs on the IoT platform. Contact IoT platform maintenance personnel. Parent topic: Data Collection
Restarting a Cluster (Deprecated) Function This API is used to restart a data node in a cluster, which will interrupt services. To restart all nodes in a cluster, you are advised to use [Restart Cluster V2] (RestartClusterMultiRole.xml).
When the operation role is role, the value is one or multiple node types (such as ess, ess-master, ess-client, and ess-cold). Response Parameters Status code: 200 Request succeeded. None Example Requests Restart nodes of all or some types in the current cluster.
Response Parameters QuerySingleDeviceInfoOutDTO structure Parameter Type Description deviceId String(256) Uniquely identifies a device. gatewayId String(256) Identifies a gateway. nodeType Enum Indicates the node type.
Updating a Client (Versions Earlier Than 3.x) This section applies to clusters of versions earlier than MRS 3.x. For MRS 3.x or later, see Updating a Client (Version 3.x or Later).
Check whether appId in the request path (URL) is correct. 500 50252 Internal server error. An internal server error occurs. Recommended handling: An internal error occurs on the IoT platform. Contact IoT platform maintenance personnel. Parent topic: Data Collection
For example, you can choose a cluster management scale of 50 or 200 nodes when creating the cluster. The flavors of the master nodes are influenced by the cluster scale. Higher cluster scales require higher flavors of the master nodes.

Application The client of the instance, which is the application running on an Elastic Cloud Server (ECS). DCS Memcached instances are compatible with the Memcached protocol, and can be accessed through open-source clients.
BMS nodes can be created in a CCE cluster (when the tunnel network model is used). Ascend-accelerated nodes (powered by HiSilicon Ascend 310 AI processors) apply to scenarios such as image recognition, video processing, inference computing, and machine learning.

Record the IP address of the node where the client is to be installed and the IP address of the active Master node (active OMS node).
Master A master node is the central management node, which manages the association between all tablets, tablet servers, and replicas. Only one acting master (leader master) exists in the cluster at a time.

Enter the load balancer name (in the format of mas-xxx), set the listening port (ranging from 30000 to 40000), and set the protocol type (using HTTP or HTTPS requests for calling the inference model). Click OK.
If there are no client nodes in the cluster, data nodes will need to additionally handle cluster access and data analytics requests; if there are no master nodes, data nodes will need to provide cluster management. Master nodes (ess-master): optional.
Select the platform type based on the type of the node where the client is to be installed (select x86_64 for the x86 architecture and aarch64 for the Arm architecture) and click OK.
Options: ess: data node ess-cold: cold data node ess-master: master node. ess-client: client node Table 4 EsflavorsVersionsFlavorsResp Parameter Type Description cpu Integer Definition: Number of CPU cores of an instance.
Response Parameters Status Code: 200 OK Parameter Type Description deviceId String(256) Uniquely identifies a device. The value of this parameter is allocated by the IoT platform during device registration. psk String(32) Indicates a random PSK.
