Pentaho Data Integrator's installation structure
Before you start the application, the big data plug-in needs to know what Hadoop configuration you are using.
Figure
10-2
shows the structure of the PDI plugins directory, and specifically, the big data plug-in. It shows that the
pentaho-big-data-plugin resides within the plugins directory. This directory contains a file called plugin.properties
(Figure
10-2
), which needs to be altered so that PDI knows which Hadoop version it is connecting to. To determine
which PDI plugin version to use, you check the Pentaho URL
http://wiki.pentaho.com/display/BAD/Configuring+
Pentaho+for+your+Hadoop+Distro+and+Version
, which provides a mapping of PDI plugin to Hadoop version.
