# Using the Apache Vanilla Hadoop driver Although the Apache Vanilla Hadoop driver is not shipped as installed with PDI as with the Apache Hadoop driver, once you install this driver, you can directly connect to plain Hadoop clusters, commonly known as Apache Vanilla Hadoop clusters. As a best practice when working with plain Hadoop clusters, use the Apache Vanilla Hadoop driver for expanded functionality beyond the pre-installed Apache Hadoop driver for both secure and unsecured environments. For plain Hadoop clusters, the Apache Vanilla Hadoop driver supports a range of services including HDFS file copy, big data file formats (such as ORC, Avro, and Parquet), Hive operations, MapReduce jobs, and Sqoop. --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.pentaho.com/pdia-data-integration/10.2-data-integration/advanced-topics-pentaho-data-integration-overview/connecting-to-a-hadoop-cluster-with-the-pdi-client-article/using-the-apache-vanilla-hadoop-driver-connecting-tp-hadoop-cluster-with-pdi-client.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
