{excerpt} !Common Images^new-icon.png! How to set up and configure Pentaho (Kettle, Pentaho Data Integration, Pentaho Business Analytics Suite) for your specific Hadoop distribution.{excerpt}

*{color:red}This page applies to Kettle, Pentaho Data Integration (DI) and Pentaho Business Analytics (BA) Suite version 5.0 only.  For Kettle 4.4 (or Pentaho BA suite 4.8) see [this page|BAD:4.4 Configuring Pentaho for your Hadoop Distro and Version].{color}*

_NOTE: Pentaho is pre-configured for Apache Hadoop 0.20.2. If you are using  this distribution and version, no further configuration is required._

Pentaho  supports different versions of Hadoop distributions from many vendors  such as Apache, Cloudera, DataStax, Hortonworks, Intel, and MapR. How  can Pentaho support so many Hadoop distributions? The secret is that  Pentaho uses an abstraction layer, called a _shim_, that connects  to the different Hadoop distributions. A shim is a small library that  intercepts API calls and either redirects or handles them, or changes  parameters. Periodically, Pentaho develops new shims as vendors develop  new Hadoop distributions and versions. These big data shims are tested  and certified by Pentaho engineers.  

*The following Steps will help you get Pentaho set up to work with your Hadoop cluster*

#*1) *Determine the proper shim for your Hadoop Distro and version*


In the following table,  click the tab of the Hadoop distribution that you are interested in,  then locate the version of the distribution you want to use. Note the  name of the corresponding shim and the minimum version of the Pentaho  software that supports it.
For example,  if you want to use the Cloudera's CDH 4.2.1, click the Cloudera tab,  then look in the Hadoop version column. CDH4.2.x is supported with shim  cdh42. You need to have Pentaho Business Analytics (or Pentaho Data  Integration) version 5.0 or later installed to use this shim.

h2. Get Hadoop Distribution Shim

# **2) If  the Hadoop distribution you want is supported*

Determine whether  the  shim is included with the Pentaho software or if you need to  download  the shim from our site. If you need to download the shim,  click the *Download* link for the shim. Go to [BAD:Install Hadoop Distribution Shim]  for instructions on how to install the shim.

#*3) *If the Hadoop distribution you want isn't listed in the table.*

* Check the [archives|https://pentaho.app.box.com/50Shims] for older shims.  If you find the shim you want there, download it, then go to [Install Hadoop Distribution Shim|http://wiki.pentaho.com/display/BAD/Install+Hadoop+Distribution+Shim] for instructions on how to install the shim.
* Look at the following table of Jira cases. The shim you want might be scheduled for development, but not yet released.
* If you still can't find the shim, but want request that Pentaho develop one, [fill out a Jira ticket|http://pedroalves-bi.blogspot.com/2013/12/on-continuous-effort-to-try-to-improve.html].
* If you still can't find the shim, but want to develop it yourself, check out the [Hadoop Configuration page|http://wiki.pentaho.com/display/BAD/Hadoop+Configurations] for more information.

{anchor:SetActiveShim}

h2. Set Active Hadoop Distribution

*NOTE:  If you want to set MapR as the active distribution, go to the* *[Special Pentaho Configuration Instructions for Your Hadoop Distributions|Special Pentaho Configuration Instructions for Hadoop Distributions]** page.*

Specify  which Hadoop Distribution you want to make active. Do this for each  Pentaho component that you want to access the Hadoop distribution from.  Pentaho components include the DI and BA Servers as well as design tools  such as Spoon, Report Designer, and Metadata Editor. Note that only one  distribution can be active at a time; so each time you want to change  the distribution, you will need to reset the active Hadoop distribution.

      1. If you have not done so already, stop the components (Spoon, DI Server, BA Server, Report Designer, Metadata Editor) from which you want to access the Hadoop distribution.

      2. Do these things for each Pentaho component that you want to access the Hadoop distribution from.

      3. Navigate to the directory that contains the *plugin.properties* file for the component.
* DI Server - *data-integration-server/pentaho-solutions/system/kettle/plugins/pentaho-big-data-plugin*
* BA Server - *biserver-ee/pentaho-solutions/system/kettle/plugins/pentaho-big-data-plugin*
* Spoon - *data-integration/plugins/pentaho-big-data-plugin*
* Report Designer - *report-designer/plugins/pentaho-big-data-plugin*
* Metadata Editor - *metadata-editor/plugins/pentaho-big-data-plugin*

     4. Open the *plugin.properties* file.   

      5. Set the *active.hadoop.configuration* property to match the name of  the shim you want to make active. For example, if the name of the shim  is *cdh42*, then the code would look like this: *active.hadoop.configuation=cdh42*.

     6. Save and close the *plugin.properties* file.

     7. If you want to configure CDH 5 to use Map Reduce 1 instead of Map Reduce 2, follow the instructions in the [Special Pentaho Configuration Instructions for Your Hadoop Distributions|Special Pentaho Configuration Instructions for Hadoop Distributions] page.

     8. Start the component.

h2. Next Steps
