 # HugeGraph + HBase Backend

 This guide covers running HugeGraph with HBase backend.

 > **Deprecation notice:** The HBase backend is deprecated and is planned for removal in HugeGraph 2.0. Existing deployments should plan a migration to a maintained backend.

 > All commands below run from the repository root (this project folder).

 Use this once at the start of your terminal session:

 ```bash
 ROOT_DIR="$(git rev-parse --show-toplevel 2>/dev/null || pwd)"
 cd "$ROOT_DIR"

 ```

 </details>

 After either path is up, run the shared tests below.

 ## Common Testing Steps

 ### Apache HugeGraph Persistent Runbook (REST Engine)

 ### Prerequisites and Constants

 - Base URL: `http://localhost:8080`
 - Graph target name: `hugegraph`
 - Storage backend: persistent (HBase/RocksDB/HStore)

 ---

 ### Step 1: Purge Database (Fresh Restart)

 Wipe any conflicting test records and data schema.

 ```bash
 curl -X DELETE "http://localhost:8080/graphspaces/DEFAULT/graphs/hugegraph/clear?confirm_message=I%27m+sure+to+delete+all+data"
 ```

 Status `204 No Content` confirms success.

 ---

 ### Step 2: Provision Structural Schema

 1) Register property keys:

 ```bash
 curl -X POST -H "Content-Type: application/json" \
   -d '{"name": "name", "data_type": "TEXT", "cardinality": "SINGLE"}' \
   "http://localhost:8080/graphs/hugegraph/schema/propertykeys"
 ```

 2) Register vertex label (PRIMARY_KEY):

 ```bash
 curl -X POST -H "Content-Type: application/json" \
   -d '{"name": "person", "id_strategy": "PRIMARY_KEY", "properties": ["name"], "primary_keys": ["name"]}' \
   "http://localhost:8080/graphs/hugegraph/schema/vertexlabels"
 ```

 3) Register edge label:

 ```bash
 curl -X POST -H "Content-Type: application/json" \
   -d '{"name": "knows", "source_label": "person", "target_label": "person", "properties": []}' \
   "http://localhost:8080/graphs/hugegraph/schema/edgelabels"
 ```

 ---

 ### Step 3: Populate Graph Elements

 1) Batch write vertices (Alice and Bob):

 ```bash
 curl -X POST -H "Content-Type: application/json" \
   -d '[{"label": "person", "properties": {"name": "Alice"}}, {"label": "person", "properties": {"name": "Bob"}}]' \
   "http://localhost:8080/graphs/hugegraph/graph/vertices/batch"
 ```

 Response should include IDs similar to `1:Alice` and `1:Bob`.

 2) Create directed edge (Alice knows Bob):

 ```bash
 curl -X POST -H "Content-Type: application/json" \
   -d '{"label": "knows", "outV": "1:Alice", "inV": "1:Bob", "properties": {}}' \
   "http://localhost:8080/graphs/hugegraph/graph/edges"
 ```

 ---

 ### Step 4: Synchronous Verification and Traversal

 1) Verify target K-hop output:

 ```bash
 curl -s "http://localhost:8080/graphs/hugegraph/traversers/kout?source=%221:Alice%22&direction=OUT&max_depth=1"
 ```

 Expected output: `{"vertices":["1:Bob"]}`

 2) Verify relation path structure:

 ```bash
 curl -s "http://localhost:8080/graphs/hugegraph/traversers/rays?source=%221:Alice%22&direction=OUT&label=knows&max_depth=1"
 ```

 Expected output contains: `rays":[{"objects":["1:Alice","1:Bob"]}]`

 ---

 ### Troubleshooting Cheat Sheet

 - URI syntax error: do not append literal `"` inside bare URLs. Use URL-encoded values (`%22`).
 - Property missing errors: prefer native `/traversers/*` APIs for synchronous reads.

 ---

 ## Cleanup

 Run cleanup only after testing is complete.

 ### Standalone HugeGraph + Docker HBase

 ```bash
 cd "$SERVER_DIR" && ./bin/stop-hugegraph.sh
 cd "$ROOT_DIR"
 docker compose -p hg-hbase -f docker/hbase/docker-compose.hbase.yml down -v
 ```

 ### Docker HugeGraph + Docker HBase

 ```bash
 docker rm -f hg-server-init >/dev/null 2>&1 || true
 docker rm -f hg-server-dev-hbase
 docker compose -p hg-hbase -f docker/hbase/docker-compose.hbase.yml down -v
 ```

 ---

 ## Troubleshooting

 | Symptom | Fix |
 |---|---|
 | `UnknownHostException: hbase:16000` | HugeGraph container is not on same Docker network as HBase. Verify `HBASE_NETWORK` and `--network`. |
 | RocksDB logs in server output | `backend=rocksdb` still active; re-run backend config and restart. |
 | `TableNotFoundException` on API calls | Tables not initialized; re-run `init-store.sh` from selected path. |
 | Port 8182 already in use | `lsof -i :8182` then `kill <PID>`. |
 | HBase container not starting | Check `lsof -i :2181`; increase Docker memory to >= 4 GB. |

 ---

 ## Verification Checklist

 - [ ] `backend=hbase` in `hugegraph.properties`
 - [ ] Server logs show HBase client messages (not RocksDB/HStore)
 - [ ] HBase tables exist in `default_hugegraph:*`
 - [ ] REST runbook queries return expected graph data
 - [ ] Data survives server restart
