Within the Cloudera Operational Database User Interface, the Nodes
tab, located in the Databases > Database Manager page, provides users with the ability to inspect information about the host group
nodes of the cluster.
Cloudera Operational Database accommodates a diverse range of node types, each designed
to fulfill distinct roles within the cluster's architectural framework.
The node types supported by the Cloudera Operational Database include:
Master: Manages metadata and orchestrates cluster operations.
Leader: Coordinates distributed processes to guarantee high
availability.
Gateway: Serves as the access point for client applications seeking
interaction with the cluster.
Strongmeta: Ensures the integrity and consistency of metadata
management for large clusters.
Worker: Executes data processing and storage functions within the
cluster.
Edge: Enables installation of its applications within the cluster with
simplified setup requirements.
Each of these node types is instrumental in upholding the operational database's efficient and
dependable performance. Detailed information, such as the Interface ID, Fully Qualified Domain
Name (FQDN), Instance Type, Subnet ID, Availability Zone, Public IP address, and Private IP
address, is available for each host node group.
