Hadoop (HDFS) Connector - XML and Maven Support - Mule 4

If you manually code a Mule app in XML, either from the Anypoint Studio XML editor or from a text editor, configure access to the connector in your app by adding reference namespace statements to your XML Mule flow and a dependency in the Apache Maven POM file.

You can avoid this manual process by using Anypoint Studio. When you add the connector in Studio, Studio automatically populates the XML code with the connector’s namespace and schema location, and adds a dependency to the pom.xml file.

Add a Reference Namespace Statement for the Connector

Paste the following code inside the mule tag of the header of your configuration XML:

http://www.mulesoft.org/schema/mule/hdfs
http://www.mulesoft.org/schema/mule/hdfs/current/mule-hdfs.xsd

This example shows how the namespace statements are placed in the XML:

<mule xmlns:hdfs="http://www.mulesoft.org/schema/mule/hdfs"
	xmlns="http://www.mulesoft.org/schema/mule/core"
	xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.mulesoft.org/schema/mule/core
	http://www.mulesoft.org/schema/mule/core/current/mule.xsd
	http://www.mulesoft.org/schema/mule/hdfs
	http://www.mulesoft.org/schema/mule/hdfs/current/mule-hdfs.xsd">

Add a POM File Dependency

The Apache Maven pom.xml file generated by Anypoint Studio contains Mule app connector dependencies. When you code a Mule app manually, include this XML snippet in your POM file to enable access to this connector:

<dependency>
	<groupId>org.mule.connectors</groupId>
    <artifactId>mule-hdfs-connector</artifactId>
    <version>6.0.3</version>
    <classifier>mule-plugin</classifier>
</dependency>

Verify that the connector version corresponds to the one you are using.
