Applies to: SQL Server SSIS Integration Runtime in Azure Data Factory

The HDFS File Destination component enables an SSIS package to write data to a HDFS file. The supported file formats are Text, Avro, and ORC.

To configure the HDFS File Destination, drag and drop the HDFS File Source on the data flow designer and double-click the component to open the editor.

HDFS File Destination Editor

Options

Configure the following options on the General tab of the Hadoop File Destination Editor dialog box.

Field Description
Hadoop Connection Specify an existing Hadoop Connection Manager or create a new one. This connection manager indicates where the HDFS files are hosted.
File Path Specify the name of the HDFS file.
File format Specify the format for the HDFS file. The available options are Text, Avro, and ORC.
Column delimiter character If you select Text format, specify the column delimiter character.
Column names in the first data row If you select Text format, specify whether the first row in the file contains column names.

After you configure these options, select the Columns tab to map source columns to destination columns in the data flow.

Prerequisite for ORC File Format

Java is required to use ORC file format. Architecture (32/64-bit) of the Java build should match that of the SSIS runtime to use. The following Java builds have been tested.
