CData Cmdlets for HDFS

Overview

The CData Cmdlets PowerShell Module for HDFS allows developers to write PowerShell scripts with connectivity to HDFS. The cmdlets abstract the underlying data source into tables, views, and stored procedures that can be used to both retrieve and update data. The representation of HDFS as a relational database gives the cmdlets a uniform interface and also enables you to execute SQL to HDFS.

Key Features

• Real-time access to HDFS data in Windows PowerShell.
• Pipe row objects directly from HDFS into other cmdlets as input.
• Streamlined installation via the Powershell Gallery.
