Additional configuration required to allow access to a CDH 5.x 0 cluster configured for MapReduce 1. This feature was removed in CDH 5.1. |
Before you start
These steps assume that you have already followed the Set Active Hadoop Distribution instructions and are completing your shim setup for a CDH 5.x 0 distribution. If you have not, or don't understand what any of this means, you should read Configuring Pentaho for your Hadoop Distro and Version.
Configuring MapReduce 1
CDH 5.x 0 is configured to use MapReduce 2 by default. If you want your cluster is set up to use MapReduce 1 instead, you will need to change a properties file. If you are not sure what version of MapReduce your CDH 5 cluster is using, check with your system administrator.
- Navigate to the CDH5.x 0 shim folder located in the hadoop-configurations folder that matches shim you previously configured. For example: cdh50, cdh51 etc. These steps will refer to that directory as cdhXX. This folder is different for each application and is located:
- DI Server - data-integration-server/pentaho-solutions/system/kettle/plugins/pentaho-big-data-plugin/cdhXX
- BA Server - biserver-ee/pentaho-solutions/system/kettle/plugins/pentaho-big-data-plugin/cdhXX
- Spoon - data-integration/plugins/pentaho-big-data-plugin/cdhXX
- Edit the config.properties file.
- Change the shim.current.config property from mr2 to mr1. It should look like:
Code Block shim.current.config=mr1
- Save and close the file.
