[PR] doc(server): sync backend-hbase with master [hugegraph-doc]
bitflicker64 opened a new pull request, #477:
URL: https://github.com/apache/hugegraph-doc/pull/477
Syncs the HBase backend documentation with hugegraph master (`36811483a`). The HBase backend had no page of its own: the only coverage was the option table in `config-option.md` and four commented lines in `config-guide.md`, so the namespace and table layout, the Kerberos flow, the pre-split behavior, the supported HBase version and the local `docker/hbase` setup were undocumented.
| page | what was wrong | what changed | source (file:line on master) |
|---|---|---|---|
| config/config-backend-hbase.md (en, cn) | page did not exist | new page, `weight: 7`, using `config-https.md` as the frontmatter and layout template | hugegraph-server/hugegraph-hbase/ |
| config/config-backend-hbase.md | no statement of the deprecation status | overview notes the backend is deprecated and planned for removal in 2.0, and that 1.7.0+ ships only hstore, rocksdb, hbase, memory | hugegraph-server/README.md:11, docker/hbase/README.md:5, hugegraph-server/hugegraph-dist/src/main/java/org/apache/hugegraph/dist/RegisterUtil.java:43 |
| config/config-backend-hbase.md | supported HBase version undocumented | client jars pinned to 2.6.5, HBase 2.x required server side (pre-2.0 loses inclusive stop rows), CI and the Docker image use 2.6.5 | hugegraph-server/hugegraph-hbase/pom.xml:31, hugegraph-server/hugegraph-hbase/src/main/java/org/apache/hugegraph/backend/store/hbase/HbaseSessions.java:749, hugegraph-server/hugegraph-dist/src/assembly/travis/install-hbase.sh:22, docker/hbase/Dockerfile:21 |
| config/config-backend-hbase.md | how to select the backend undocumented | `backend=hbase` plus `serializer=hbase`, with a note on why `binary` is not equivalent, plus the note that a `rocksdb-only` build has no HBase provider | hugegraph-server/hugegraph-dist/src/main/java/org/apache/hugegraph/dist/RegisterUtil.java:93, hugegraph-server/hugegraph-hbase/src/main/java/org/apache/hugegraph/backend/store/hbase/HbaseSerializer.java:29, hugegraph-server/hugegraph-test/pom.xml:310, hugegraph-server/hugegraph-dist/pom.xml:38 |
| config/config-backend-hbase.md | option list incomplete elsewhere | all fifteen `HbaseOptions` keys with defaults, allowed ranges and the HBase property each one maps to, grouped as the Options class groups them | hugegraph-server/hugegraph-hbase/src/main/java/org/apache/hugegraph/backend/store/hbase/HbaseOptions.java:44-162, HbaseSessions.java:122-157 |
| config/config-backend-hbase.md | Kerberos flow undocumented | the four Kerberos keys plus `hbase.hbase_site`, and what the backend sets on the connection when `hbase.kerberos_enable=true`; also that `hbase.hbase_site` is loaded regardless | HbaseSessions.java:141-155 |
| config/config-backend-hbase.md | namespace and table layout undocumented | namespace derivation (`default_hugegraph` by default), the three stores `m`/`g`/`s` and their table names, the single `f` column family, the aggregation coprocessor, which tables are pre-split, and the `M` meta table kept across truncate | HbaseStoreProvider.java:26-30, hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/backend/store/BackendProviderFactory.java:61-70, hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/backend/store/BackendStoreProvider.java:28-30, HbaseTable.java:72, HbaseSessions.java:90-91, HbaseStore.java:270-289, HbaseStore.java:588-597 |
| config/config-backend-hbase.md | local test setup undocumented | the `docker/hbase` compose flow, the advertised hostname variables, the five published ports, the maven profile to run the tests, and the teardown command | docker/hbase/docker-compose.hbase.yml:19-62, docker/hbase/entrypoint.sh:20-51, docker/hbase/README.md:29-38 |
| config/config-backend-hbase.md | limitations undocumented | the features the backend reports as unsupported, count-only aggregation, and that snapshots are unimplemented | HbaseFeatures.java:30-141, HbaseTable.java:150-153, hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/backend/store/BackendStore.java:180-186 |
Paths in the source column are relative to the hugegraph repository root; the `Hbase*.java` files without a directory live in `hugegraph-server/hugegraph-hbase/src/main/java/org/apache/hugegraph/backend/store/hbase/`.
Only the two new pages are touched. Three problems found in pages owned by other modules are reported separately and left unedited: the `hbase.krb5_conf` default in `config-option.md` is written `etc/krb5.conf` instead of `/etc/krb5.conf`, `hbase.truncate_timeout` is missing from that table, and the hbase block quoted in `config-guide.md` predates the `hbase.enable_partition` / `hbase.vertex_partitions` / `hbase.edge_partitions` lines now in the shipped template.
