# Big data tutorials

Pentaho big data tutorials provide examples of how you can use Pentaho technology as part of your overall big data strategy. Each section is a series of scenario-based tutorials that demonstrate the integration between Pentaho and Hadoop using a sample data set.

The following videos help demonstrate using PDI to work with Hadoop from both inside and outside a Hadoop cluster.

* Loading data into Hadoop from outside the Hadoop cluster is a 5-minute video that demonstrates moving data using a PDI job and transformation: <https://www.youtube.com/watch?v=Ylekzmd6TAc>
* Use [Pentaho MapReduce](/pdia-data-integration/10.2-data-integration/pdi-job-entries-reference-overview/pentaho-mapreduce.md) to interactively design a data flow for a MapReduce job without writing scripts or code. Here is a 12 minute video that provides an overview of the process: <https://www.youtube.com/watch?v=KZe1UugxXcs>
