Import: Hive

Creates a data contract from a Hive database by reading DESCRIBE FORMATTED for each table — including the full declared column types, the partition columns, and the comments on tables and columns.

datacontract import hive \
  --source localhost \
  --database sales \
  --output datacontract.yaml

--source is the host of your HiveServer2. Add --port if it doesn't listen on the default 10000, and repeat --table to import only specific tables (by default every table and view in the database is imported).

Hive reports a complete type string, so varchar(10), decimal(10,2) and struct<city:string,zip:string> are taken verbatim and match what datacontract test reads back. Arrays, maps, and structs are expanded into items, map and nested properties.

The generated contract includes a ready-to-test servers block, so you can run datacontract test datacontract.yaml immediately afterwards — see the Hive connection guide for the full 5-minute walkthrough and troubleshooting.

Credentials are the same ones datacontract test uses — see the Hive Reference.

Only have a DDL file? Use datacontract import sql --dialect hive.

All options: datacontract import hive.
