+#### `sys` Schema and `information_schema` Schema
+
+`Hive Schema Tool` is located in the Docker Image at
`/opt/hive/bin/schematool`.
+
+By default, system schemas such as `information_schema` for HiveServer2 are
not created.
+To create system schemas for a HiveServer2 instance,
+users need to configure HiveServer2 to use a remote Hive Metastore Server and
use a database other than embedded Derby for the Hive Metastore Server.
+
+Assuming `Maven` and `Docker CE` are installed, a possible use case is as
follows.
+Create a `compose.yaml` file in the current directory,
+
+```yaml
+services:
+ some-postgres:
+ image: postgres:17.2-bookworm
+ environment:
+ POSTGRES_PASSWORD: "example"
+ metastore-standalone:
+ image: apache/hive:4.0.1
+ depends_on:
+ - some-postgres
+ environment:
+ SERVICE_NAME: metastore
+ DB_DRIVER: postgres
+ SERVICE_OPTS: >-
+ -Djavax.jdo.option.ConnectionDriverName=org.postgresql.Driver
+
-Djavax.jdo.option.ConnectionURL=jdbc:postgresql://some-postgres:5432/postgres
+ -Djavax.jdo.option.ConnectionUserName=postgres
+ -Djavax.jdo.option.ConnectionPassword=example
+ volumes:
+ -
~/.m2/repository/org/postgresql/postgresql/42.7.5/postgresql-42.7.5.jar:/opt/hive/lib/postgres.jar
+ hiveserver2-standalone:
+ image: apache/hive:4.0.1
+ depends_on:
+ - metastore-standalone
+ environment:
+ SERVICE_NAME: hiveserver2
+ IS_RESUME: true
+ SERVICE_OPTS: >-
+ -Djavax.jdo.option.ConnectionDriverName=org.postgresql.Driver
+
-Djavax.jdo.option.ConnectionURL=jdbc:postgresql://some-postgres:5432/postgres
+ -Djavax.jdo.option.ConnectionUserName=postgres
+ -Djavax.jdo.option.ConnectionPassword=example
+ -Dhive.metastore.uris=thrift://metastore-standalone:9083
+ volumes:
+ -
~/.m2/repository/org/postgresql/postgresql/42.7.5/postgresql-42.7.5.jar:/opt/hive/lib/postgres.jar
+```
+
+Then execute the shell command as follows to initialize the system schemas in
HiveServer2.
+
+```shell
+mvn dependency:get -Dartifact=org.postgresql:postgresql:42.7.5
+docker compose up -d
+docker compose exec hiveserver2-standalone /bin/bash
+/opt/hive/bin/schematool -initSchema -dbType hive -metaDbType postgres -url
jdbc:hive2://localhost:10000/default
+exit
+```
Review Comment:
@dengzhhu653
- There is still a question in the current PR: Should I require users to
install `Maven` in advance through `SDKMAN!`? The unit test I wrote in
https://github.com/linghengqian/hive-server2-jdbc-driver/pull/23 prefers to use
`Dockerfile` to dynamically create Docker Image, but the Hive documentation
seems to like to assume that users know how to use `Maven`.
```dockerfile
FROM alpine:3.21.2 AS prepare
RUN apk add --no-cache wget
RUN wget
https://repo1.maven.org/maven2/org/postgresql/postgresql/42.7.5/postgresql-42.7.5.jar
--directory-prefix=/opt/hive/lib
FROM apache/hive:4.0.1
COPY --from=prepare /opt/hive/lib /opt/hive/lib
```
