Java 1.6.x or higher versions are good for Hadoop, preferably from Sun. Linux and Windows are the supported operating system for Hadoop, but BSD, Mac OS/X, and Solaris are more famous for working.
As of my last knowledge update in January 2022, the platform and Java version requirements for running Hadoop may have evolved. However, as of that time, Hadoop was primarily designed to run on Unix-based systems like Linux. It can also run on Windows, but Unix-based systems are more common in production environments.
For the Java version, Hadoop traditionally relied on Java. At that time, Hadoop 2.x versions were commonly compatible with Java 7 and 8. It’s important to note that newer versions of Hadoop may have increased compatibility with newer Java versions.
To get the most accurate and up-to-date information, I recommend checking the official Apache Hadoop documentation or release notes for the specific version you are working with. This will provide the most current information regarding platform and Java version compatibility.
