Resource management

Aggregate statistical system operation data

One-stop management of tenant resources, computing resources (CPU/memory/IO), storage resources (HDFS), service resources (HBase.…)

Visual multi-level tenant management, matching with the enterprise organizational structure, simplifies system resource allocation and management

Tenant resource isolation based on container mechanism, escorting tenant SLA

A multi-level tenant model that matches the organizational structure of the enterprise, different departments correspond to different tenants, and tenants can be dynamically added or deleted as needed

Before deploying Kerberos services, LD must be deployedAP service

The LDAP service must be deployed on the same node as the Kerberos service

Deploying the same node for Kerberos service and LDAP service facilitates data access and improves performance

LDAP services can be shared by multiple clusters

HBasePeriod refreshMemstore, silentthink period is 1Hour

When the number of files in WALs reaches a threshold

The total size of the MemStore in the Region has reached the preset Flush Size threshold

The ratio of the total memory occupied by the MemStore to the total memory of the RegionServer exceeds the preset threshold size

Supports threshold control for the total number of established connections

Supports threshold control for the number of connections established by each user

Supports threshold control on the number of connections established by a specific user

Supports threshold control of the number of connections established per unit time

The RegionServer is generally deployed with the NameNode of the HDFS cluster to realize the data storage function.

Data processing and computing unit of HBase

Regionserver is the data service process of HBase, responsible for processing user data read and write requests

Manage all Regions, Regions can be migrated between RegionServers
