Explanation

All four options are correct because ZooKeeper serves as a universal distributed coordination backbone in FusionInsight HD, providing services like configuration management, leader election, service discovery, and distributed locking across the entire platform. HBase (A) depends on ZooKeeper most critically - it uses it for master election, region server registration, and tracking cluster state, making ZooKeeper a hard dependency. Loader (B), FusionInsight's data ingestion component, relies on ZooKeeper to coordinate distributed task scheduling and ensure consistency across concurrent data loading jobs. Hive (C) leverages ZooKeeper for HiveServer2 high-availability coordination and service registry, so clients can discover active instances. Spark (D) uses ZooKeeper for master failover and leader election in high-availability mode, preventing a single point of failure in the cluster.

Since all choices are correct, there are no distractors to eliminate - the question tests whether you know ZooKeeper's breadth of applicability, not just its most famous use case (HBase).

Memory tip: Think of ZooKeeper as the "traffic controller" of FusionInsight HD - virtually every major component that needs to coordinate across nodes (elect a leader, register a service, or synchronize state) calls on ZooKeeper. If a component runs distributed, ZooKeeper likely manages it.
