# Before you begin PDI contains all the job entries and transformation steps required for working with Hadoop, Cassandra, and MongoDB. Your cluster administrator can set up the Pentaho Server to communicate with most Hadoop distributions. See [Set up Pentaho to connect to a Hadoop cluster](https://github.com/pentaho/documentation/blob/main/PDIA/9.3/Install/Pentaho%20configuration/Pentaho%20Configuration%20-%20Config%20Overview%20\(article%20cp\)/Tasks%20to%20be%20Performed%20by%20an%20IT%20Administrator%20-%20Config%20Overview/Set%20up%20the%20Pentaho%20Server%20to%20connect%20to%20a%20Hadoop%20cluster=GUID-0866C02D-7364-4F94-9D0E-4C1EEA19FC41=11=en=.md) for more information. For a list of supported big data technology, including which configurations of Hadoop are currently supported, see the [Components Reference](/install/9.3-install/components-reference.md). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
