This article outlines how to use the Copy Activity in an Azure Data Factory or Synapse Analytics pipeline to copy data from Hive. It builds on the copy activity overview article that presents a general overview of copy activity.
Important
The Hive connector version 2.0 provides improved native Hive support. If you are using the Hive connector version 1.0 in your solution, please upgrade your Hive connector before September 30, 2025. Refer to this section for details on the difference between version 2.0 and version 1.0.
Supported capabilities
This Hive connector is supported for the following capabilities:
Supported capabilities | IR |
---|---|
Copy activity (source/-) | ① ② |
Mapping data flow (source/-) | ① |
Lookup activity | ① ② |
① Azure integration runtime ② Self-hosted integration runtime
For a list of data stores that are supported as sources/sinks by the copy activity, see the Supported data stores table.
The service provides a built-in driver to enable connectivity, therefore you don't need to manually install any driver using this connector.
The connector supports the Windows versions in this article.
Prerequisites
If your data store is located inside an on-premises network, an Azure virtual network, or Amazon Virtual Private Cloud, you need to configure a self-hosted integration runtime to connect to it.
If your data store is a managed cloud data service, you can use the Azure Integration Runtime. If the access is restricted to IPs that are approved in the firewall rules, you can add Azure Integration Runtime IPs to the allow list.
You can also use the managed virtual network integration runtime feature in Azure Data Factory to access the on-premises network without installing and configuring a self-hosted integration runtime.
For more information about the network security mechanisms and options supported by Data Factory, see Data access strategies.
Note
Version 2.0 is supported with the self-hosted integration runtime version 5.54 or above.
Getting started
To perform the Copy activity with a pipeline, you can use one of the following tools or SDKs:
- The Copy Data tool
- The Azure portal
- The .NET SDK
- The Python SDK
- Azure PowerShell
- The REST API
- The Azure Resource Manager template
Create a linked service to Hive using UI
Use the following steps to create a linked service to Hive in the Azure portal UI.
Browse to the Manage tab in your Azure Data Factory or Synapse workspace and select Linked Services, then click New:
Search for Hive and select the Hive connector.
Configure the service details, test the connection, and create the new linked service.

Copy activity properties
For a full list of sections and properties available for defining activities, see the Pipelines article. This section provides a list of properties supported by Hive source.

Mapping data flow properties
The hive connector is supported as an inline dataset source in mapping data flows. Read using a query or directly from a Hive table in HDInsight. Hive data gets staged in a storage account as parquet files before getting transformed as part of a data flow.
Source properties
The below table lists the properties supported by a hive source. You can edit these properties in the Source options tab.
Name | Description | Required | Allowed values | Data flow script property |
---|---|---|---|---|
Store | Store must be hive |
yes | hive |
store |
Format | Whether you are reading from a table or query | yes | table or query |
format |
Schema name | If reading from a table, the schema of the source table | yes, if format is table |
String | schemaName |
Table name | If reading from a table, the table name | yes, if format is table |
String | tableName |
Query | If format is query , the source query on the Hive linked service |
yes, if format is query |
String | query |
Staged | Hive table will always be staged. | yes | true |
staged |
Storage Container | Storage container used to stage data before reading from Hive or writing to Hive. The hive cluster must have access to this container. | yes | String | storageContainer |
Staging database | The schema/database where the user account specified in the linked service has access to. It is used to create external tables during staging and dropped afterwards | no | true or false |
stagingDatabaseName |
Pre SQL Scripts | SQL code to run on the Hive table before reading the data | no | String | preSQLs |
Source example
Below is an example of a Hive source configuration:
These settings translate into the following data flow script:
source(
allowSchemaDrift: true,
validateSchema: false,
ignoreNoFilesFound: false,
format: 'table',
store: 'hive',
schemaName: 'default',
tableName: 'hivesampletable',
staged: true,
storageContainer: 'khive',
storageFolderPath: '',
stagingDatabaseName: 'default') ~> hivesource
Known limitations
- Complex types such as arrays, maps, structs, and unions are not supported for read.
- Hive connector only supports Hive tables in Azure HDInsight of version 4.0 or greater (Apache Hive 3.1.0)
- By default, Hive driver provides "tableName.columnName" in sink. If you do not wish to see the table name in the column name, then there are two ways to fix this. a. Check the setting "hive.resultset.use.unique.column.names" in Hive server side and set it to false. b. Use column mapping to rename the column name.
Data type mapping for Hive
When you copy data from and to Hive, the following interim data type mappings are used within the service. To learn about how the copy activity maps the source schema and data type to the sink, see Schema and data type mappings.
Hive data type | Interim service data type (for version 2.0) | Interim service data type (for version 1.0) |
---|---|---|
TINYINT | Sbyte | Int16 |
SMALLINT | Int16 | Int16 |
INT | Int32 | Int32 |
BIGINT | Int32 | Int64 |
BOOLEAN | Boolean | Boolean |
FLOAT | Single | Single |
DOUBLE | Double | Double |
DECIMAL | Decimal | Decimal |
STRING | String | String |
VARCHAR | String | String |
CHAR | String | String |
TIMESTAMP | DateTimeOffset | DateTime |
DATE | DateTime | DateTime |
BINARY | Byte[] | Byte[] |
ARRAY | String | String |
MAP | String | String |
STRUCT | String | String |

Version 2.0 | GA version available | • The self-hosted integration runtime version should be 5.54 or above. • The default value of enableSSL is true. enableServerCertificateValidation is supported. trustedCertPath , useSystemTrustStore , allowHostNameCNMismatch and allowSelfSignedServerCert are not supported. • TINYINT is read as SByte data type. • TIMESTAMP is read as DateTimeOffset data type. • Using ';' to separate multiple hosts (only when serviceDiscoveryMode is enabled) is not supported. • HiveServer1 and HiveThriftServer are not supported for ServerType . • Username authentication type is not supported. SASL transport protocol only supports UsernameAndPassword authentication type. Binary transport protocol only supports Anonymous authentication type. • serviceDiscoveryMode , zooKeeperNameSpace and useNativeQuery are not supported. |
Upgrade the Hive connector from version 1.0 to version 2.0
In Edit linked service page, select version 2.0 and configure the linked service by referring to Linked service properties version 2.0.
The data type mapping for the Hive linked service version 2.0 is different from that for the version 1.0. To learn the latest data type mapping, see Data type mapping for Hive.
Apply a self-hosted integration runtime with version 5.54 or above.
