Using AOM to Monitor Hosts Hosts include the Elastic Cloud Server (ECS) and Bare Metal Server (BMS). AOM can monitor the hosts purchased during CCE and ServiceStage cluster creation as well as those purchased in non-CCE and -ServiceStage environments.
Go to the client decompression path FusionInsight_Cluster_1_Services_ClientConfig\Hive\config and manually import the configuration file to the configuration file directory (usually the resources folder) of the Hive sample project.
Status Codes Status Code Description 200 Request succeeded. Error Codes See Error Codes. Parent Topic: Server Installation and Configuration
A 200 response indicates that the server has received the request and starts to process the request. Only when the response body contains ETag, the copy is successful, or the copy fails.
Configuring Cluster Logs Function This API is used to select the master node components whose logs are reported to LTS. Calling Method For details, see Calling APIs.
Figure 3 HA among master and standby nodes within an AZ Cross-AZ DR Within a Region The master and standby nodes of a DCS instance (single-node type not included) can be deployed across AZs (in different equipment rooms).

Preparing for Hive Development and Operating Environment Preparing Development Environment Hive applications can be developed by using the Java (JDBC and HCatalog), Python, Python 3 API. The following table describes the development and operating environment to be prepared.

The following pseudocode shows how the Seconds_Behind_Master value is calculated. if (SQL thread is running) //If the SQL thread is started { if (SQL thread processed all the available relay log) //If the binlog pulled by the I/O thread from the master node is the same
Only letters, digits, hyphens (-), and underscores (_) are allowed. role String Definition Node type, indicating the role of a node in an instance. Range master (primary node) or slave (standby node) status String Definition Node status.
Master Node AZs You can check how many master nodes are supported in a cluster. To check data such as the resource usage of the master nodes, click View Monitoring in the upper right corner to go to the Monitoring (Monitoring Center) page.
