The multi-service feature allows components of the same type to be installed in a cluster and be managed by FusionInsight Manager. This helps resolve resource isolation and performance problems.

The newly added instances have the same functional modules as existing services, such as logs, users, and shell commands. FusionInsight Manager provides unified management for HBase, Hive, and Spark/Spark2x instances, including monitoring, alarming, and starting or stopping services. When importing and exporting data using Loader, extracting metadata using Metadata, creating roles, backing up and restoring data, or developing applications, the system administrator needs to select specific service instances based on the actual situation.

The multi-service feature can linearly improve the overall service performance. The service instance resources can be customized. Tenants can associate with different service instances to enable services to run in isolated resources, improving customer satisfaction and user experience.


The three sets of HBase components (HBase, HBase-1, and HBase-2) installed in the same cluster are called three service instances.


This feature is under license control by the node number. The required licenses depend on the total number of nodes in each service instances.


For details about the multi-service feature supported by each component, see 3.3-Table Memory requirements and deployment principles of service roles in Deployment Scheme > Software Deployment Scheme.

For components that support the multi-service feature, you can install multiple service instances for the initial installation or add services to clusters where services have been installed. For details, see section Installing a Service in FusionInsight HD 6.5.0 Software Installation.


  • The multi-service feature does not support co-host deployment. Specifically, multiple services and roles of the same service cannot be deployed on the same host.
  • The multi-service feature does not allow a service to connect to two underlying services at the same time.

    For example, one Hive service cannot be connected to multiple DBServices.
