Configuring the MapReduce Adapter

Installing the Hadoop Client Libraries

For a Permanent license, rename your Permanent license file to master.lic.

For a Demo license, create a file called demo.lic, then type the demo code into the demo.lic file.

Place the file in the 

 directory.

Restart the master:

Windows:

Click 

 in the Service Control Manager. 

UNIX:

Enter 

The master will read and apply the license when it starts.

To validate that the license was applied, select 

 from 

 main menu. 

Installing the Hadoop Client Libraries

Hadoop client libraries are required for processing the Hadoop-related DataMover, Hive, MapReduce, and Sqoop jobs. 
As of CWA 6.3, Hadoop libraries are not included with CWA. Instead, we provide a Maven script (POM.xml) to install the 
required libraries.

If you do not already have Maven, you must download and install it. Obtain the POM.xml file from the folder/directory 
named "Hadoop" in the CD and run the file script to download the required Hadoop client libraries. Instructions for 
obtaining Maven and downloading the Hadoop libraries are included in these sections:





 The instructions here are for Windows.

Installing Maven

If you do not have Maven installed, follow the instructions below. 

Maven Prerequisites


JDK must be installed.



The JAVA_HOME environment variable must be set and point to your JDK.

Download maven 3 or above from 

Unzip apache-maven-<3 or above>-bin.zip.

Add the bin directory of the created directory (for example, apache-maven-3.3.9) to the PATH environment variable
