Tutorial: Query Apache Hive with ODBC and PowerShell

Microsoft ODBC drivers provide a flexible way to interact with different kinds of data sources, including Apache Hive. You can write code in scripting languages like PowerShell that use the ODBC drivers to open a connection to your Hive cluster, pass a query of your choosing, and display the results.

In this tutorial, you'll do the following tasks:

  • Download and install the Microsoft Hive ODBC driver
  • Create an Apache Hive ODBC data source linked to your cluster
  • Query sample information from your cluster using PowerShell

If you don’t have an Azure subscription, create a free account before you begin.


Before you begin this tutorial, you must have the following items:

Install Microsoft Hive ODBC driver

Download and install the Microsoft Hive ODBC Driver.

Create Apache Hive ODBC data source

The following steps show you how to create an Apache Hive ODBC data source.

  1. From Windows, navigate to Start > Windows Administrative Tools > ODBC Data Sources (32-bit)/(64-bit). An ODBC Data Source Administrator window opens.

    OBDC data source administrator

  2. From the User DSN tab, select Add to open the Create New Data Source window.

  3. Select Microsoft Hive ODBC Driver, and then select Finish to open the Microsoft Hive ODBC Driver DSN Setup window.

  4. Type or select the following values:

    Property Description
    Data Source Name Give a name to your data source
    Host(s) Enter CLUSTERNAME.azurehdinsight.net. For example, myHDICluster.azurehdinsight.net
    Port Use 443.
    Database Use default.
    Mechanism Select Windows Azure HDInsight Service
    User Name Enter HDInsight cluster HTTP user username. The default username is admin.
    Password Enter HDInsight cluster user password. Select the checkbox Save Password (Encrypted).
  5. Optional: Select Advanced Options.

    Parameter Description
    Use Native Query When it's selected, the ODBC driver does NOT try to convert TSQL into HiveQL. Use this option only if you're 100% sure that you're submitting pure HiveQL statements. When connecting to SQL Server or Azure SQL Database, you should leave it unchecked.
    Rows fetched per block When fetching a large number of records, tuning this parameter may be required to ensure optimal performances.
    Default string column length, Binary column length, Decimal column scale The data type lengths and precisions may affect how data is returned. They cause incorrect information to be returned because of loss of precision and truncation.

    Advanced DSN configuration options

  6. Select Test to test the data source. When the data source is configured correctly, the test result shows SUCCESS.

  7. Select OK to close the Test window.

  8. Select OK to close the Microsoft Hive ODBC Driver DSN Setup window.

  9. Select OK to close the ODBC Data Source Administrator window.

Query data with PowerShell

The following PowerShell script is a function that ODBC to query a Hive cluster.

function Get-ODBC-Data {

   [string]$query=$(throw 'query is required.'),
   [PSCredential] $cred = (Get-Credential)  

   $conn = New-Object System.Data.Odbc.OdbcConnection
   $uname = $cred.UserName

   $pswd = (New-Object System.Net.NetworkCredential -ArgumentList "", $cred.Password).Password
   $conn.ConnectionString = "DSN=$dsn;Uid=$uname;Pwd=$pswd;"
   $cmd = New-object System.Data.Odbc.OdbcCommand($query,$conn)

   $ds = New-Object system.Data.DataSet

   (New-Object system.Data.odbc.odbcDataAdapter($cmd)).fill($ds) #| out-null

The following code snippet uses the function above to execute a query on the Interactive Query cluster that you created at the beginning of the tutorial. Replace DATASOURCENAME with the Data Source Name that you specified on the Microsoft Hive ODBC Driver DSN Setup screen. When prompted for credentials, enter the username and password that you entered under Cluster login username and Cluster login password when you created the cluster.


$query = "select count(distinct clientid) AS total_clients from hivesampletable"

Get-ODBC-Data -query $query -dsn $dsn

Clean up resources

When no longer needed, delete the resource group, HDInsight cluster, and storage account. To do so, select the resource group where the cluster was created and click Delete.
