Explanation
Hadoop 2.x introduced YARN (Yet Another Resource Negotiator), which revolutionized cluster resource management and became the industry-standard version adopted by major cloud platforms, including ECS-based big data services. Hadoop 1.x is an outdated legacy version that predates YARN and lacks the scalability and resource management features required by modern cloud deployments. Hadoop 3.x introduced further improvements (like erasure coding and support for multiple NameNodes), but the ECS environment in question was designed and certified specifically around the 2.x architecture. Hadoop 4.x does not exist as a released version and is simply a distractor.
Memory tip: Think "2 = YARN, and YARN = Cloud-ready." ECS support aligns with the generation of Hadoop that made distributed computing practical for enterprise cloud use - that's 2.x.
