+# Hive Regression Local Environment
+
+This document records the local Docker and regression configuration needed to run:
+
+```bash
+regression-test/suites/external_table_p0/hive/
+```
+
+## Required Thirdparty Components
+
+Run Hive2 and Hive3 through the thirdparty launcher:
+
+```bash
+./docker/thirdparties/run-thirdparties-docker.sh -c hive2,hive3 --hive-mode refresh
+```
+
+The Hive startup script may also start `mysql` automatically. Both
+`docker-compose/hive/hive-2x_settings.env` and
+`docker-compose/hive/hive-3x_settings.env` default `JFS_CLUSTER_META` to:
+
+```bash
+mysql://root:123456@(127.0.0.1:3316)/juicefs_meta
+```
+
+Because of that setting, `run-thirdparties-docker.sh` treats local MySQL 5.7 as
+an implicit dependency for Hive.
+
+Each Hive version starts its own compose services:
+
+- Hive2: `hive2-server`, `hive2-metastore`, `hadoop2-namenode`,
+  `hadoop2-datanode`, `hive2-metastore-postgresql`
+- Hive3: `hive3-server`, `hive3-metastore`, `hadoop3-namenode`,
+  `hadoop3-datanode`, `hive3-metastore-postgresql`
+- MySQL 5.7: required by the default JuiceFS metadata URI when using the local
+  `127.0.0.1:3316` endpoint
+
+The Hive p0 directory does not require these components by default:
+
+- `pg`
+- `iceberg`
+- `minio`
+- `hudi`
+- `kerberos`
+- `ranger`
+
+`test_external_catalog_hive.groovy` has a Ranger-specific branch guarded by
+`enableRangerTest`; if this option is not set to `true`, that branch is skipped.
+
+## Current Running Containers Observed
+
+The following relevant containers were running when checked with
+`sudo docker ps`:
+
+- Hive3 stack: `hive3-server`, `hive3-metastore`, `hadoop3-datanode`,
+  `hadoop3-namenode`, `hive3-metastore-postgresql`; all healthy
+- Hive2 stack: `hive2-server`, `hive2-metastore`, `hadoop2-datanode`,
+  `hadoop2-namenode`, `hive2-metastore-postgresql`; all healthy
+- MySQL 5.7: `mysql-doris--syt--mysql_57-1`, healthy, published as
+  `127.0.0.1:3316 -> 3306`
+
+Other Doris thirdparty containers were also running, but they are not required
+for `external_table_p0/hive/`:
+
+- PostgreSQL 14 on `5442`
+- Iceberg REST, Spark, Postgres, and MinIO
+- Oracle on `1521`
+- ClickHouse on `8123`
+- SQLServer on `1433`
+- OceanBase on `2881`
+
+The observed Hive2/Hive3 and MySQL compose projects came from another checkout
+under `/mnt/disk2/suyiteng/doris`, not from this worktree. PostgreSQL and
+Iceberg compose projects came from this worktree.
+
+## Regression Configuration
+
+The Hive p0 suite directly reads these keys from
+`regression-test/conf/regression-conf.groovy`:
+
+```groovy
+enableHiveTest
+externalEnvIp
+hive2HmsPort
+hive2HdfsPort
+hive3HmsPort
+hive3HdfsPort
+hdfsUser
+```
+
+It also uses framework helpers backed by:
+
+```groovy
+brokerName
+hdfsPasswd
+hdfsFs
+```
+
+For local Hive2/Hive3 Docker with default ports, the relevant values are:
+
+```groovy
+enableHiveTest = true
+
+hive2HmsPort = 9083
+hive2HdfsPort = 8020
+hive2ServerPort = 10000
+hive2PgPort = 5432
+
+hive3HmsPort = 9383
+hive3HdfsPort = 8320
+hive3ServerPort = 13000
+hive3PgPort = 5732
+
+hdfsUser = "doris-test"
+brokerName = "broker_name"
+hdfsPasswd = ""
+```
+
+`externalEnvIp` must be the address that Doris BE can use to reach the Hive
+Docker services. For a fully local setup this is usually:
+
+```groovy
+externalEnvIp = "127.0.0.1"
+```
+
+If BE runs in a context where `127.0.0.1` is not the Docker host, use the host
+IP selected by `run-thirdparties-docker.sh` through `IP_HOST`.
+
+## Config Gaps Noted In regression-conf.groovy.bak
+
+`regression-test/conf/regression-conf.groovy.bak` already contains the core Hive
+keys listed above. The notable follow-ups are:
+
+- `externalEnvIp` was set to `172.20.32.136`; verify this is reachable from BE,
+  or replace it with `127.0.0.1` for local host-mode Docker.
+- FE/JDBC addresses in the file used `9033`, `9022`, and `8033`; align these
+  with the current Doris worktree cluster ports before running regression.
+- `enableRangerTest` is not present. This is acceptable for the Hive p0 suite
+  because the Ranger-specific branch is guarded and skipped unless explicitly
+  enabled.
+
+## Thirdparty Script Settings
+
+Before starting Hive through `run-thirdparties-docker.sh`, set a unique
+`CONTAINER_UID` in:
+
+```bash
+docker/thirdparties/custom_settings.env
+```
+
+The default `CONTAINER_UID="doris--"` is rejected by the startup script.
+
+Hive baseline restore also depends on these settings:
+
+```bash
+s3Endpoint
+s3BucketName
+HIVE_BASELINE_VERSION
+HIVE_BASELINE_TARBALL_CACHE
+```
+
+If baseline download is unavailable, place the matching tarball manually under
+`HIVE_BASELINE_TARBALL_CACHE`.
