Which of the following Hadoop distributions are supported on Oracle Cloud Infrastructure?

Cloudera is recognized as a Hadoop distribution that is compatible with Oracle Cloud Infrastructure. It provides a comprehensive suite for big data management and analytics, integrating various components of the Hadoop ecosystem, such as HDFS, YARN, and MapReduce, along with additional tools for data ingestion, processing, and visualization.

Cloudera's distribution is specifically designed to support enterprise-level data workloads and is often optimized for various cloud environments, including Oracle's. This compatibility allows organizations leveraging Oracle Cloud to utilize Cloudera for managing large datasets and running scalable applications effectively.

Other options, while relevant within the big data landscape, do not represent Hadoop distributions specifically supported by Oracle Cloud Infrastructure. Apache Spark and Apache Flink are processing frameworks that can run on top of Hadoop but are not Hadoop distributions themselves. Microsoft HDInsight is a cloud service provided by Microsoft for big data processing that is not compatible with Oracle Cloud. Thus, the focus on Cloudera as the correct choice is due to its established support and integration within Oracle's cloud ecosystem.
