Copy data from HBase using Azure Data Factory or Synapse Analytics

APPLIES TO: Azure Data Factory Azure Synapse Analytics

This article outlines how to use the Copy Activity in an Azure Data Factory or Synapse Analytics pipeline to copy data from HBase. It builds on the copy activity overview article that presents a general overview of copy activity.

Supported capabilities

This HBase connector is supported for the following capabilities:

Supported capabilities	IR
Copy activity (source/-)	① ②
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.

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.

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 Hbase using UI

Use the following steps to create a linked service to Hbase in the Azure portal UI.

1. Browse to the Manage tab in your Azure Data Factory or Synapse workspace and select Linked Services, then click New:

   • Azure Data Factory
   • Azure Synapse

   

2. Search for Hbase and select the Hbase connector.

   

3. Configure the service details, test the connection, and create the new linked service.

   

Connector configuration details

The following sections provide details about properties that are used to define Data Factory entities specific to HBase connector.

Linked service properties

The following properties are supported for HBase linked service:

Property	Description	Required
type	The type property must be set to: HBase	Yes
host	The IP address or host name of the HBase server. (i.e. [clustername].azurehdinsight.cn， 192.168.222.160)	Yes
port	The TCP port that the HBase instance uses to listen for client connections. The default value is 9090. If you connect to Azure HDInsights, specify port as 443.	No
httpPath	The partial URL corresponding to the HBase server, e.g. /hbaserest0 when using HDInsights cluster.	No
authenticationType	The authentication mechanism to use to connect to the HBase server. Allowed values are: Anonymous, Basic	Yes
username	The user name used to connect to the HBase instance.	No
password	The password corresponding to the user name. Mark this field as a SecureString to store it securely, or reference a secret stored in Azure Key Vault.	No
enableSsl	Specifies whether the connections to the server are encrypted using TLS. The default value is false.	No
trustedCertPath	The full path of the .pem file containing trusted CA certificates for verifying the server when connecting over TLS. This property can only be set when using TLS on self-hosted IR. The default value is the cacerts.pem file installed with the IR.	No
allowHostNameCNMismatch	Specifies whether to require a CA-issued TLS/SSL certificate name to match the host name of the server when connecting over TLS. The default value is false.	No
allowSelfSignedServerCert	Specifies whether to allow self-signed certificates from the server. The default value is false.	No
connectVia	The Integration Runtime to be used to connect to the data store. Learn more from Prerequisites section. If not specified, it uses the default Azure Integration Runtime.	No

Example for HDInsights HBase:

{
    "name": "HBaseLinkedService",
    "properties": {
        "type": "HBase",
        "typeProperties": {
            "host" : "<cluster name>.azurehdinsight.cn",
            "port" : "443",
            "httpPath" : "/hbaserest0",
            "authenticationType" : "Basic",
            "username" : "<username>",
            "password": {
                "type": "SecureString",
                "value": "<password>"
            },
