Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.pentaho.com/pdia-data-integration/9.3-data-integration/pdi-job-entries-reference-overview/pentaho-mapreduce/use-pdi-outside-and-inside-the-hadoop-cluster/big-data-tutorials.md). # 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: * Use [Pentaho MapReduce](/pdia-data-integration/9.3-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: --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.pentaho.com/pdia-data-integration/9.3-data-integration/pdi-job-entries-reference-overview/pentaho-mapreduce/use-pdi-outside-and-inside-the-hadoop-cluster/big-data-tutorials.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
