About the Hive collector
Use this collector to harvest metadata for Hive tables and columns across the enterprise systems and make it searchable and discoverable in data.world.
Important
The Hive collector can be run on-premise using Docker or JAR files.
Note
The latest version of the Collector is 2.326. To view the release notes for this version and all previous versions, please go here.
What is cataloged
The collector catalogs the following information.
Object | Information cataloged |
|---|---|
Columns | Name, Description, JDBC type, Column Type |
Table | Name, Description, Last DDL time, Row count, Total size, Raw data size, File count, Erasure coded file count, Bucketing version, Is external, External table purge, Is translated to external, Column stats accurate |
Views | Name, description, SQL definition |
Schema | Identifier |
Database | Type, Name, Identifier, Server, Port, Environment, JDBC URL |
Relationships between objects
By default, the harvested metadata includes catalog pages for the following resource types. Each catalog page has a relationship to the other related resource types. If the metadata presentation for this data source has been customized with the help of the data.world Solutions team, you may see other resource pages and relationships.
Resource page | Relationship |
|---|---|
Table | Columns, Table Indexes |
Columns | Table, Table Indexes |
Table Indexes | Columns |
Schema | Database that contains Schema, Table that is part of Schema |
Database | Schema contained in Database |
Lineage for Hive
The following lineage information is collected by the Hive collector.
Object | Lineage available |
|---|---|
Column in View | The collector identifies The associated column in an upstream view or table:
|
Authentication supported
The collector supports username/password authentication to Hive.
IRI consistency between Hive Metastore and Hive collectors
If you are using both the Hive Metastore collector and the Hive collector to catalog the same Hive environment, configure them with matching parameters to ensure they produce identical IRIs for the same resources. This prevents duplicate entries in data.world and maintains a unified view of your metadata.
Hive Metastore collector parameter | Hive collector parameter |
|---|---|
--hive-server-host | --server |
--hive-server-port | --port |
--hive-database | --database |
--hive-database-id | --database-id |
When these values match across both collectors, metadata from either source will resolve to the same resources in your catalog, ensuring consistent resource identification regardless of which collector harvested the metadata.
