----------------------------------
Summary: Support for HBase multi-tenant management view (was: HBase
multi-tenant mangement view Management View)
> Support for HBase multi-tenant management view
> ----------------------------------------------
>
> Key: AMBARI-26526
> URL: https://issues.apache.org/jira/browse/AMBARI-26526
> Project: Ambari
> Issue Type: New Feature
> Reporter: Nikita Pande
> Assignee: Nikita Pande
> Priority: Major
>
> *Problem Statement:*
> While Apache HBase provides a comprehensive set of features to support
> enterprise requirements—including multitenancy through region server
> grouping, namespaces, and quotas, as well as critical data management
> functions like snapshots and backups—access to these features is largely
> limited to command-line tools and Java APIs. This technical barrier creates
> significant challenges for administrators who may not possess deep HBase or
> programming expertise.
> As a result, routine operational tasks—such as tenant onboarding, resource
> allocation, quota enforcement, snapshot creation, and backup management—are
> often complex, time-consuming, and prone to human error. The lack of a
> unified, intuitive graphical interface also increases the risk of
> misconfiguration, slows down troubleshooting.
> To address these challenges and democratize HBase administration, there is a
> clear need for enhanced UI capabilities, such as those provided by Ambari
> Views. By extending the UI to support not only multitenancy management but
> also snapshot and backup operations, administrators of varying skill levels
> can more easily and reliably perform essential tasks. This will help reduce
> operational overhead, improve data reliability, and ensure consistent policy
> enforcement—ultimately making HBase more accessible, secure, and manageable
> for organizations of all sizes.
> h3. Impact on Operations
> These challenges result in administrators spending excessive time on routine
> and critical data management tasks, encountering a higher risk of
> configuration errors, and having difficulty troubleshooting issues or
> ensuring consistent policy enforcement. The absence of a unified, intuitive
> interface not only complicates tenant onboarding and resource allocation, but
> also makes operations like snapshot creation and backup management
> error-prone and difficult to audit.
> ----
> h3. Proposal: Ambari View for HBase Multi-Tenancy, Snapshot, and Backup
> Management
> To simplify and streamline HBase administration, we propose implementing a
> dedicated Ambari View for HBase RSGroup, tenant, snapshot, and backup
> management. By enabling these key operations through an intuitive UI,
> administrators can easily onboard tenants, allocate resources, manage
> snapshots and backups, and track changes—without needing to master the
> technical details of region server groups, namespaces, quotas, or data
> protection operations.
> This enhancement will provide a user-friendly interface that abstracts the
> complexity of HBase internals. For example, onboarding a new tenant through
> the UI would automatically handle namespace creation, user setup, quota
> assignment, and resource allocation. Similarly, creating a snapshot or
> scheduling a backup can be accomplished with simple guided workflows.
> Administrators will no longer need in-depth knowledge of HBase commands or
> architecture to perform tasks accurately, reliably, and efficiently.
> Ambari’s extensible 'views' feature allows for the development of such
> dedicated interfaces without altering core HBase or Ambari functionality,
> ensuring seamless integration and maintainability.
> ----
> h3. Key Operations of the Proposed HBase View Page
> *RSGroups Overview:*
> Administrators will have a graphical overview of all RSGroups, including
> server distribution, table and namespace assignments. This visualization
> allows for rapid identification of imbalances or misconfigurations.
> *Simplified Tenant, Snapshot, and Backup Management:*
> The UI will guide administrators step-by-step through creating, modifying,
> and deleting RSGroups, adding or removing servers, assigning tables and
> namespaces, and managing quotas. Onboarding a new tenant becomes a single
> workflow that automates namespace creation, user onboarding, and resource
> allocation. Snapshots and backups can be created, scheduled, and restored via
> intuitive wizards, improving data protection and recovery processes.
> *Quota, Namespace, and User Management:*
> Administrators can manage quotas, namespaces, and users directly from the UI,
> ensuring consistent enforcement of organizational policies and simplifying
> day-to-day management.
> ----
> h3. Implementation Details
> The new view will be introduced as a project under {{contrib/views}} in
> Ambari. Key steps include:
> * Defining the view with all necessary metadata.
> * Creating APIs for all required HBase RSGroup, snapshot, backup, quota, and
> user management operations.
> * Implementing REST endpoints to interact with HBase and related systems.
> * Building a React-based UI to provide a modern, responsive user experience.
> * Ensuring UI consistency with Ambari’s design language and offering visual
> workflows for all core operations.
> A proof-of-concept for RSGroup management using Ambari View has already been
> developed, demonstrating technical feasibility and the value of this approach
> by our team ([~anchalk1] , [~nikitapande] ). Thanks to [~nihaljain.cs]
> [~rajeshbabu] [~brahma] for guiding the team and providing valuable inputs.
> ----
> h3. Future Scope
> Beyond RSGroup and tenant management, this feature is designed for
> extensibility. It can be expanded to provide comprehensive UI-driven
> management for HBase snapshots, backups, quotas, namespaces, and user
> administration, empowering organizations to manage their HBase environments
> more efficiently, securely, and reliably.
