Distributed caching with memory/disk tiers +**Storage Layer**: Cloud object stores (S3, GCS, Azure Blob, MinIO) + +### Key Features + +#### Production Readiness +- **High Availability**: Multi-replica deployments with anti-affinity +- **Resource Management**: CPU/memory requests and limits for all components +- **Health Monitoring**: Liveness and readiness probes +- **Persistent Storage**: PVCs for Alluxio journal and cache +- **Security**: Cloud authentication with IRSA/Workload Identity/Managed Identity + +#### Development Experience +- **Local Testing**: Complete setup with MinIO in KinD +- **Smoke Tests**: Automated validation of all functionality +- **Documentation**: Step-by-step guides for all scenarios +- **Flexibility**: Multiple configuration examples + +#### Cloud Integration +- **AWS S3**: Native S3 support with IRSA authentication +- **Google Cloud**: GCS integration with Workload Identity +- **Azure Blob**: Azure Blob Storage with Managed Identity +- **Multi-cloud**: Alluxio enables seamless multi-cloud deployments + +### Usage Examples + +#### Quick Local Development +```bash +# Deploy locally with MinIO +helm install accumulo-dev ./charts/accumulo -f ./charts/accumulo/values-dev.yaml + +# Run tests +helm test accumulo-dev + +# Access services +kubectl port-forward svc/accumulo-dev-monitor 9995:9995 +``` + +#### Production AWS Deployment +```bash +# Deploy on EKS with S3 +helm install accumulo-prod ./charts/accumulo -f values-production-aws.yaml +``` + +#### Validation +```bash +# Run comprehensive smoke tests +helm test accumulo-prod + +# Manual verification +kubectl exec -it deployment/accumulo-prod-manager -- /opt/accumulo/bin/accumulo shell -u root +``` + +### Benefits Achieved + +#### Operational Excellence +- **Reduced Complexity**: No HDFS cluster to manage +- **Cloud Native**: Leverages managed object storage +- **Auto-scaling**: Kubernetes-native scaling capabilities +- **Monitoring**: Built-in web interfaces and metrics + +#### Cost Optimization +- **Storage Efficiency**: Pay-per-use object storage +- **Resource Elasticity**: Scale components independently +- **Multi-tenancy**: Shared Alluxio cache across workloads + +#### Performance +- **Intelligent Caching**: Hot data in memory/SSD tiers +- **Optimized Writes**: Per-path write policies for different data types +- **Network Efficiency**: Distributed caching reduces cloud API calls + +## Next Steps + +### Immediate +1. **Deploy and Test**: Use the development setup for validation +2. **Customize**: Adapt production values for your specific environment +3. **Monitor**: Set up metrics collection and alerting + +### Future Enhancements (Beyond Scope) +- Horizontal Pod Autoscaler configurations +- Advanced compaction strategies and tuning +- Migration tools from HDFS-based deployments +- Helm operator for GitOps workflows + +## Conclusion + +This implementation provides a complete, production-ready solution for running Apache Accumulo on Kubernetes with cloud storage. The focus on operational simplicity aligns with the goal of minimizing ops overhead while maintaining the power and flexibility of Accumulo for big data workloads. + +The chart successfully abstracts the complexity of distributed storage through Alluxio, enabling teams to focus on their core applications rather than infrastructure management. \ No newline at end of file diff --git a/charts/accumulo/Chart.yaml b/charts/accumulo/Chart.yaml new file mode 100644 index 00000000000..dcf0548aa75 --- /dev/null +++ b/charts/accumulo/Chart.yaml @@ -0,0 +1,48 @@ +# +# Licensed to the Apache Software Foundation (ASF) under one +# or more contributor license agreements.

+### Accumulo Components +- **Manager**: Cluster coordination and metadata management +- **TabletServers**: Handle read/write operations and host tablets +- **Monitor**: Web UI for cluster monitoring and management +- **Garbage Collector**: Cleans up unused files +- **Compactors**: Background compaction of tablets + +### Alluxio Components +- **Master**: Metadata management and coordination +- **Workers**: Distributed caching layer with memory and disk tiers + +### Supporting Services +- **ZooKeeper**: Coordination service (embedded or external) +- **MinIO**: Object storage for development (optional) + +## Storage Architecture + +``` ++------------------+ +------------------+ +------------------+ +| Accumulo | | Alluxio | | Cloud Storage | +| Components |--->| (Cache Layer) |--->| (S3/GCS/...) | ++------------------+ +------------------+ +------------------+ +``` + +Alluxio provides: +- **Unified namespace**: Single view across multiple storage systems +- **Intelligent caching**: Hot data cached in memory/SSD for performance +- **Write optimization**: Different write modes per path (WAL, tables, temp) + +## Monitoring + +### Web Interfaces + +- **Accumulo Monitor**: `http://:9995/` +- **Alluxio Master**: `http://:19999/` + +### Prometheus Metrics (Optional) + +Enable Prometheus metrics collection: + +```yaml +monitoring: + prometheus: + enabled: true +``` + +## Security + +### Cloud Authentication + +The chart supports multiple authentication methods: + +- **Service Account**: Use Kubernetes service accounts with cloud IAM +- **Access Keys**: Direct credential configuration +- **Workload Identity**: GKE Workload Identity +- **IRSA**: EKS IAM Roles for Service Accounts +- **Managed Identity**: Azure Managed Identity + +### Network Security + +- All inter-component communication uses Kubernetes services +- Optional Istio service mesh support +- Configurable network policies (not included in this chart) + +## Troubleshooting + +### Common Issues + +1. **Pods stuck in Pending**: Check resource requests and node capacity +2. **Storage connection issues**: Verify cloud credentials and bucket permissions +3. **Alluxio mount failures**: Check storage provider configuration + +### Debugging Commands + +```bash +# Check Accumulo Manager logs +kubectl logs deployment/accumulo-manager + +# Check Alluxio Master status +kubectl port-forward svc/accumulo-alluxio-master 19999:19999 +curl http://localhost:19999/ + +# Run shell commands +kubectl exec -it deployment/accumulo-manager -- /opt/accumulo/bin/accumulo shell -u root +``` + +### Smoke Tests + +Run the built-in smoke tests to validate deployment: + +```bash +helm test +``` + +The smoke test validates: +- All services are accessible +- Accumulo table operations work +- Alluxio integration is functional +- Monitor web interface is available + +## Upgrade Guide + +### From Previous Versions + +1. **Backup your data**: Ensure data is safely stored in cloud object storage +2. **Update values**: Review new configuration options +3. **Perform upgrade**: `helm upgrade ./charts/accumulo` + +### Rolling Updates + +The chart supports rolling updates for most components: +- TabletServers can be updated rolling +- Compactors support rolling updates +- Manager updates may cause brief unavailability + +## Development + +### Local Development Setup + +1. **Install KinD**: For local Kubernetes cluster +2. **Deploy with dev values**: Use `values-dev.yaml` +3. **Access services**: Use port-forwarding for local access + +```bash +# Create local cluster +kind create cluster --name accumulo-dev + +# Install chart +helm install accumulo-dev ./charts/accumulo -f ./charts/accumulo/values-dev.yaml + +# Port forward to access services +kubectl port-forward svc/accumulo-dev-monitor 9995:9995 +kubectl port-forward svc/accumulo-dev-alluxio-master 19999:19999 +``` + +### Contributing + +1. **Test changes**: Always test with smoke tests +2. **Update documentation**: Keep README and values comments current +3. **Validate templates**: Use `helm template` and `helm lint` + +## License + +This chart is provided under the Apache License 2.0, same as
