Apache Hbase Icon HBase Cmdlets

An easy-to-use set of PowerShell Cmdlets offering real-time access to Apache Hbase data. The Cmdlets allow users to easily read, write, update, and delete live data - just like working with SQL server.

Pipe HBase Data to CSV in PowerShell

Use standard PowerShell cmdlets to access HBase tables.

The CData Cmdlets Module for HBase is a standard PowerShell module offering straightforward integration with HBase. Below, you will find examples of using our ApacheHBase Cmdlets with native PowerShell cmdlets.

Creating a Connection to Your HBase Data

Set the Port and Server to connect to Apache HBase.

$conn = Connect-ApacheHBase  -Server "$Server" -Port "$Port"

Selecting Data

Follow the steps below to retrieve data from the Customers table and pipe the result into to a CSV file:

Select-ApacheHBase -Connection $conn -Table Customers | Select -Property * -ExcludeProperty Connection,Table,Columns | Export-Csv -Path c:\myCustomersData.csv -NoTypeInformation

You will notice that we piped the results from Select-ApacheHBase into a Select-Object cmdlet and excluded some properties before piping them into an Export-Csv cmdlet. We do this because the CData Cmdlets append Connection, Table, and Columns information onto each "row" in the result set, and we do not necessarily want that information in our CSV file.

The Connection, Table, and Columns are appended to the results in order to facilitate piping results from one of the CData Cmdlets directly into another one.

Deleting Data

The following line deletes any records that match the criteria:

Select-ApacheHBase -Connection $conn -Table Customers -Where "ShipCity = New York" | Remove-ApacheHBase

Inserting and Updating Data

The cmdlets make data transformation easy as well as data cleansing. The following example loads data from a CSV file into HBase, checking first whether a record already exists and needs to be updated instead of inserted.

Import-Csv -Path C:\MyCustomersUpdates.csv | %{
  $record = Select-ApacheHBase -Connection $ApacheHBase -Table Customers -Where ("Id = `'"+$_.Id+"`'")
    Update-ApacheHBase -Connection $apachehbase -Table Customers -Columns ("CustomerName","Price") -Values ($_.CustomerName, $_.Price) -Where ("Id = `'"+$_.Id+"`'")
    Add-ApacheHBase -Connection $apachehbase -Table Customers -Columns ("CustomerName","Price") -Values ($_.CustomerName, $_.Price)

As always, our goal is to simplify the way you connect to data. With cmdlets users can install a data module, set the connection properties, and start building. Download Cmdlets and start working with your data in PowerShell today!
