Configure the Windows Client to Submit MapReduce Version 2 Applications

This section describes how to add a property that allows you to run MapReduce Version 2 applications from a Windows client.

Procedure

Before running any MapReduce Version 2 (MRv2) applications from a Windows client, add the following property to the mapred-site.xml file:

<property>
<name>mapreduce.app-submission.cross-platform</name>
<value>true</value>
</property>

The mapred-site.xml file for MapReduce applications is located in the following directory:

%MAPR_HOME%\hadoop\hadoop-2.x.x\etc\hadoop\mapred-site.xml
